Steel Grade Chemical Composition & Mechanical Properties Quick Reference

Q: What does 'per grade standard' mean in the chemistry and mechanical columns?

'Per grade standard' means the nominal chemical composition range and mechanical property requirements are defined by the governing standard for that grade — for example, ASTM A109 for SAE10xx carbon steels, EN 10132 for C45E and C67S, JIS G4051 for SxxC grades, GB/T 3077 for 42CrMo and 40Cr, and EN 10346 for coated grades. The actual values for a specific heat are always within the standard range but vary from heat to heat; they are reported on the MTC. This page does not list nominal ranges or fabricate values — refer to the standard or request the MTC for exact numbers.

A searchable, family-grouped reference of 353 steel grades stocked by HS-FINEB. Each row lists the grade, spec range, surface finish, and current stock status from live inventory. Chemical composition and mechanical property columns are marked "per grade standard" — exact values vary by heat and are reported on the mill test certificate (MTC).

At a glanceThis reference covers 353 steel grades from HS-FINEB inventory, grouped into ten families: plain carbon, alloy structural, spring and tool, stainless, electrical silicon, cold/hot rolled and coated, advanced high-strength and press-hardening, HSLA and structural, bearing, and precision nickel alloy. Stock and spec data come directly from the HS-FINEB inventory system (1,704 line items). Chemical composition (C, Mn, Si, S, P, Cr) and mechanical properties (UTS, YS, elongation, hardness) are intentionally shown as "per grade standard" because the inventory source does not contain heat-level chemistry or test data, and no values have been copied from external suppliers or standards. Use the search box and family filter to locate a grade, then request a full MTC for the exact heat analysis and mechanical test results. HS-FINEB supplies spheroidized fine blanking strip in SAE1010, SAE1035, SAE1078, 65Mn, C67S, C75S, 42CrMo, GCr15, and 22MnB5+AS with EN 10204 3.1 certification per coil.

01 — How to use

How to use this reference

This page is a lookup tool, not a substitute for a mill test certificate. Use it to confirm that a grade is stocked, check the available spec range and surface, and identify which family it belongs to.

Filter by grade name. Type any part of a grade designation into the search box at the top of the page — for example, "1078" will match SAE1078, "CrMo" will match 42CrMo, 35CrMo, and 30CrMo, and "DC04" will match DC04, DC04+ZE, and DC04-C390. The filter is case-insensitive and matches substrings, so you do not need the exact designation.

Filter by family. Use the family dropdown to narrow the tables to a single steel family — for example, select "Electrical / Silicon Steel" to see only 50WW, B35A, and B50A series grades. Select "All families" to restore the full view. The grade count next to the dropdown updates to show how many rows match the current filters.

Read the row. Each row shows the grade name, the spec range currently in inventory, the surface finish, nine chemistry and mechanical property columns, and the stock status. The chemistry and mechanical columns all read "— / per grade standard" — this is intentional and explained in the Data source & limitations section below.

Request an MTC. When you have identified a grade and need exact chemical composition or mechanical properties, follow the process in the How to request a full MTC section. The MTC reports the actual heat analysis and tensile test results for the specific coil or heat lot you will receive.

No JavaScript? The search and filter controls are progressive enhancement. If JavaScript is disabled or unavailable, all ten family tables remain fully visible and scrollable. The page is usable as a static reference without any scripting.

For guidance on which grade to choose for a fine blanking application, refer to the companion fine blanking material selection guide and the fine blanking material requirements complete guide, which define the carbon window, hardness band, and spheroidization criteria for fine blanking steel.

02 — Columns

Reading the columns

Each table has fourteen columns. The first three and the last come from HS-FINEB inventory records; the middle ten are placeholders that point to the grade standard and the MTC.

Column	Source	What it means
Grade	Inventory	The standard designation as recorded in the HS-FINEB inventory system. Designations follow SAE/AISI, EN, JIS, GB, or proprietary mill naming. Case variants (e.g. 42CRMO and 42CrMo) are deduplicated to the standard form.
Spec Range	Inventory	The thickness × width × form currently in stock, e.g. "2.51248C" means 2.5 mm × 1248 mm coil. "Full range" means multiple dimensions are stocked. "Custom sizes" means the grade is supplied to order. "—" means the inventory record does not specify a dimension.
Surface	Inventory	The as-delivered surface condition: bright, flat, smooth, skin-passed, lightly oiled, scratch-free, cold rolled, or as-rolled. Translated from the source inventory record. "—" means no surface description is recorded.
C, Mn, Si, S, P, Cr	Grade standard / MTC	Chemical composition in weight percent. All six columns show "— / per grade standard" because the inventory data does not contain heat-level chemistry. Nominal ranges are defined by the governing standard; actual values are on the MTC.
UTS (MPa)	Grade standard / MTC	Ultimate tensile strength. As-delivered values depend on the annealing or processing condition (spheroidized annealed, cold rolled, hot rolled pickled) and vary by heat. Reported on the MTC.
YS (MPa)	Grade standard / MTC	Yield strength (or 0.2% proof stress). Depends on delivery condition and grain size. Reported on the MTC.
Elong. (%)	Grade standard / MTC	Percentage elongation after fracture, measured on a standard tensile specimen (A50 or A80 depending on standard). Reported on the MTC.
Hardness	Grade standard / MTC	As-delivered hardness in HB, HRB, or HRC depending on grade and delivery condition. Varies by heat and annealing cycle; the actual tested value is reported on the MTC.
Stock	Inventory	Current inventory status with available tonnage, e.g. "In stock (86,787 t)". Tonnage reflects the inventory record at page generation and changes daily. Confirm before ordering.

The chemistry and mechanical property columns are intentionally left without numeric values. This page does not reproduce nominal composition ranges from ASTM, EN, JIS, or GB standards, and it does not copy data from any external supplier. Refer to the governing standard or request an MTC for exact values.

03 — Data source

Data source & limitations

Understanding where each data point comes from is essential for using this reference correctly. The table below summarizes the source and reliability of every column.

Inventory data. The grade name, spec range, surface finish, and stock status are extracted from the HS-FINEB inventory dataset, which contains 1,704 line items covering 353 unique steel grades. These fields are maintained by the warehouse and procurement team and reflect actual coil stock. Stock tonnage is recorded at the time of data export and may change as coils are allocated to orders or new mill deliveries arrive.

Chemical composition. The inventory dataset does not contain chemical composition data. The C, Mn, Si, S, P, and Cr columns therefore show "— / per grade standard" for every grade. This is not an oversight — it is a deliberate choice to avoid publishing nominal ranges that could be mistaken for heat-level guarantees. The nominal composition range for each grade is defined by the governing standard (ASTM A109/AISI for SAE10xx, EN 10132 for C45E/C67S, JIS G4051 for SxxC, GB/T 3077 for 42CrMo/40Cr, EN 10346 for coated grades, etc.), and the actual heat composition is reported on the MTC.

Mechanical properties. Similarly, the inventory dataset does not contain tensile test or hardness data. The UTS, YS, elongation, and hardness columns show "— / per grade standard" because as-delivered mechanical properties depend on the processing route (cold rolled, spheroidized annealed, hot rolled pickled, galvanized) and vary from heat to heat. The governing standard defines minimum or range requirements, and the actual tested values are on the MTC.

No external data. No chemical or mechanical values on this page have been copied from GNEE, TPI, Matmatch, Azom, or any other external source. If a value is not in the HS-FINEB inventory system, it is not shown. This policy ensures that every number on the page is traceable to either the HS-FINEB inventory or the customer's own MTC request.

Grade classification. Grades are grouped into ten families based on their chemical system and primary application. The classification is optimized for procurement lookup — a grade like 22MnB5+AS appears under Alloy Structural Steel because that is its standard family, even though it is also widely used as a press-hardening grade. If you cannot find a grade in the expected family, use the search box rather than browsing.

Surface translation. Surface descriptions are translated from Chinese inventory records into English. Terms like "平整" (flat), "光整" (skin-passed), "微涂油" (lightly oiled), and "精整" (finished) are mapped to their standard English equivalents. Unusual surface descriptions are retained in translated form.

Carbon Steel (Plain)

Carbon Steel (Plain) — 20 grades in stock

Plain carbon steels contain iron and carbon with only residual amounts of manganese, silicon, and trace impurities. They are the most widely supplied family at HS-FINEB, covering low-carbon drawing grades through medium-carbon machinery grades and high-carbon grades used for blades and springs. Chemical composition and mechanical property values below are per the applicable grade standard — request a mill test certificate for the exact heat analysis.

Stock and spec data are from HS-FINEB inventory records. Chemical composition (C, Mn, Si, S, P, Cr) and mechanical properties (UTS, YS, elongation, hardness) are not listed here because they vary by heat and processing condition — they are reported per heat on the mill test certificate (MTC).

Stainless Steel

Stainless Steel — 6 grades in stock

Stainless steels contain a minimum of approximately 10.5% chromium, which forms a passive chromium-oxide film that resists corrosion. The grades in HS-FINEB stock are predominantly austenitic (SUS301, 12Cr17Ni7) and martensitic stainless tool steels (7C27Mo2, 95Cr15) used for blades, cutlery, and corrosion-resistant components. Composition and mechanical values below are per grade standard; exact values vary by heat and are reported on the MTC.

Electrical / Silicon Steel

Electrical / Silicon Steel — 87 grades in stock

Electrical (silicon) steels are low-carbon, silicon-alloyed ferritic steels optimized for low core loss and high magnetic permeability in motors, generators, and transformers. Grades are designated by thickness and maximum specific loss (e.g. 50WW470 = 0.50 mm, ≤4.70 W/kg at 1.5 T / 50 Hz), with B35A and B50A series covering non-oriented fully-processed and semi-processed variants. Chemical and mechanical values are per grade standard; magnetic properties are the primary specification and are reported on the MTC.

Advanced High-Strength & Press-Hardening Steel

Advanced High-Strength & Press-Hardening Steel — 80 grades in stock

Advanced high-strength steels (AHSS) and press-hardening steels deliver ultra-high tensile strength through dual-phase (DP), complex-phase (CP), martensitic (MS), or hot-stamping microstructures. This family includes HC-series dual-phase grades (HC340/590DP through HC980/1180DP), hot-stamping grades (22MnB5+AS, Usibor1500P, BR1500HS), and coated variants for automotive structural and safety components. All composition and mechanical values are per grade standard; as-delivered properties depend on the processing route and are reported on the MTC.

HSLA & Structural Steel

HSLA & Structural Steel — 40 grades in stock

High-strength low-alloy (HSLA) and structural steels use microalloying additions (niobium, vanadium, titanium) to achieve high yield strength with good formability and weldability. This family covers QSTE TM automotive steels, S355MC–S550MC cold-formable structural grades, BS600MC/BS700MC, and B-series wheel and beam steels (B510L, B330CL). Chemistry and mechanics below are per grade standard; exact values are confirmed per heat on the MTC.

How to request a full mill test certificate

A mill test certificate (MTC) is the document that reports the actual chemical composition and mechanical properties for a specific heat or coil. Every grade on this page is available with a full MTC.

What an MTC contains. A standard EN 10204 3.1 MTC includes: the heat number, grade designation, delivery condition, full chemical composition (C, Mn, Si, S, P, Cr, Ni, Mo, V, Al, Cu, and residual elements), tensile test results (ultimate tensile strength, yield strength or 0.2% proof stress, percentage elongation), hardness readings, microstructure assessment (for grades where specified), decarburization depth (for high-carbon and spring grades), non-metallic inclusion rating per ASTM E45 or ISO 4967, and dimensional results (thickness, width, camber, flatness). For fine blanking grades, the MTC also reports the spheroidization ratio.

How to request. Email sales@fineblankingmachine.com with the following information: (1) grade name, (2) required specification — thickness, width, surface, edge condition, (3) quantity, and (4) any required certificate type (3.1 standard or 3.2 third-party witnessed). We will confirm the available heat numbers and provide the MTC for review before shipment, or include it with the shipping documents.

Certificate types. EN 10204 3.1 certificates are issued by the mill's quality department and are standard for all orders at no extra cost. EN 10204 3.2 certificates are witnessed and counter-signed by an independent third-party inspector (TUV, SGS, Bureau Veritas, or the buyer's nominated inspector) and are available for an additional fee, typically required for safety-critical automotive or aerospace applications.

Timeline. MTCs for stock coils are available within one working day of request. MTCs for mill-order material are issued at the time of production and delivered with the shipment. If you need to review the MTC before committing to an order, we can provide a representative certificate from a recent heat of the same grade — note that the actual heat you receive may have slightly different chemistry and mechanics within the standard range.

Reading the MTC. If you are new to mill test certificates, the knowledge article how to read a mill test certificate walks through each section, explains the difference between 3.1 and 3.2 certificates, and lists the common discrepancies to check for at incoming inspection. For fine blanking steel, the most critical MTC fields are carbon content, hardness band, spheroidization ratio, and decarburization depth — these are covered in detail in the fine blanking material requirements guide.

FAQ

Steel grade reference, asked and answered

Where can I get the exact chemical composition for a steel grade?

Exact chemical composition is reported on the mill test certificate (MTC) for each heat or coil. The tables on this page show "per grade standard" for all chemistry columns because the inventory data source does not contain heat-level chemical analysis, and actual composition varies between heats even within the same grade. To obtain an MTC, email sales@fineblankingmachine.com with the grade name, required specification, and quantity; we will provide the EN 10204 3.1 mill certificate with full element analysis (C, Mn, Si, S, P, Cr, Ni, Mo, V, Al, and residual elements) for the specific heat you will receive.

Are all listed grades in stock?

The Stock column in each table shows the current inventory status and tonnage from HS-FINEB inventory records. Grades marked "In stock (X t)" have available tonnage at the time of page generation. Stock levels change daily as coils are allocated to orders, so confirm availability before placing a purchase order. Grades not shown in the tables may still be available on a mill-order basis — send the grade and specification to sales@fineblankingmachine.com and we will check mill lead times. Common fine blanking grades such as SAE1078 steel strip, 65Mn spring steel, and C45E medium carbon steel are maintained as regular stock items.

Can you supply custom specifications — thickness, width, edge condition?

Yes. HS-FINEB supplies steel strip and coil in custom thicknesses, widths, and edge conditions. The Spec Range column shows the dimensions currently in inventory (for example, "2.5*1248*C" means 2.5 mm thickness by 1248 mm width in coil form, and "Full range" means multiple dimensions are stocked). For dimensions not in stock, we can slit to width, level, cut to length, or place a mill order with a typical lead time of 3–6 weeks depending on the grade and quantity. Edge options include slit edge, trimmed edge, and rounded edge. Send your drawing or specification sheet for a firm quote, and review our slitting, leveling, and cut-to-length services for processing capabilities.

What does "per grade standard" mean in the chemistry and mechanical columns?

"Per grade standard" means the nominal chemical composition range and mechanical property requirements are defined by the governing standard for that grade — for example, ASTM A109 for SAE10xx carbon steels, EN 10132 for C45E and C67S, JIS G4051 for SxxC grades, GB/T 3077 for 42CrMo and 40Cr, and EN 10346 for coated grades. The actual values for a specific heat are always within the standard range but vary from heat to heat; they are reported on the MTC. This page does not list nominal ranges or fabricate values — refer to the standard or request the MTC for exact numbers. For electrical steel grades such as 50WW470 electrical steel, the primary specification is magnetic core loss rather than mechanical properties.

How do I request a mill test certificate (MTC)?

Request an MTC by emailing sales@fineblankingmachine.com with the grade name, specification (thickness, width, surface), and quantity. MTCs are issued per coil or per heat lot and include heat number, grade, full chemical composition, tensile test results (UTS, YS, elongation), hardness, microstructure, decarburization depth, inclusion rating, and dimensional results. Standard certificates are EN 10204 3.1 (mill-issued); 3.2 certificates (third-party witnessed by TUV, SGS, or Bureau Veritas) are available on request for an additional fee. MTCs are typically delivered with the shipment, or pre-shipment on request for quality review. See the How to request a full MTC section above for the full process.
