Steel Grade Selector Tool

After setting the filters, click Find Grades. The tool scans the inline grade database and displays matching cards. Each card shows the grade name in large type, the steel family, the available spec range from inventory, the surface condition, a stock status indicator, and recommended application tags. Two action buttons follow: View product page opens the detailed grade page (or family page if no dedicated grade page exists), and Request quote opens the contact form with the grade name pre-filled in the subject line.

If no grades match your exact combination, the tool displays a friendly prompt with a View all grades link. You can also reset all filters with the Reset button and try a broader search. For grades not in the database, the CTA at the bottom of the page lets you send your specification directly — HS-FINEB typically responds within one working day.

For a deeper treatment of how these families perform in fine blanking specifically, refer to the fine blanking material requirements complete guide, which covers the carbon window, spheroidized microstructure, hardness bands and dimensional tolerances that define whether a grade can be fine blanked cleanly. The companion material selection guide provides a five-step decision framework for choosing among families.

Carbon steel vs. alloy steel for the same strength target. If your part requires through-hardening to 45–55 HRC and the section is under 12 mm, a plain carbon grade such as SAE1050 or C45E may be sufficient and costs less. For sections thicker than 12 mm, or where impact toughness after quenching is critical, switch to an alloy grade such as 42CrMo or 35CrMo — the chromium and molybdenum provide deeper hardening and a more uniform microstructure across the section. The 42CrMo alloy steel strip page details the hardenability advantage.

Spring steel: 65Mn vs. 50CrV4 vs. C67S. 65Mn is the most economical spring steel, with good hardenability up to about 10 mm section, but it is prone to decarburization and temper brittleness. 50CrV4 (equivalent to SAE6150) offers superior hardenability, higher elastic limit and better fatigue resistance for highly stressed springs such as clutch disc springs and suspension components. C67S and C75S are European-grade spring steels with tight thickness tolerances and bright surface finish, preferred for precision blanked spring parts. The 65Mn spring steel strip and C67S / C75S strip pages compare these options.

Cold rolled deep drawing: SPCC vs. SPCE vs. DC06. SPCC is commercial quality for simple bending and shallow drawing. SPCD is drawing quality for moderate depths. SPCE (and DC06, the EN equivalent) is deep drawing quality with the lowest yield strength and highest elongation, suitable for complex drawn parts such as motor housings and appliance liners. If your part has a draw ratio above 2.0 or requires zero wrinkling, specify SPCE or DC06. The SPCC / SPCD deep drawing steel page covers the full quality ladder.

Electrical steel: core loss grade selection. The three-digit number in a grade name (e.g. 470 in 50WW470) indicates the guaranteed maximum core loss in watts per kilogram at 1.5 Tesla and 50 Hz, multiplied by 100. Lower numbers mean lower core loss and higher efficiency, but also higher cost. For large industrial motors where energy cost dominates, specify a low-loss grade such as 50WW350 or B35A250. For cost-sensitive consumer appliances, 50WW600 or 50WW800 may be adequate. The 50WW470 electrical steel page explains the grade naming convention.

Press hardening vs. cold-formed AHSS. Press hardening (22MnB5+AS, BR1500HS) is the right choice when you need tensile strength above 1200 MPa in a complex shape that cannot be cold formed without cracking. The hot stamping process forms and quenches in one step, eliminating springback. For parts with strength requirements below 1000 MPa and relatively simple geometry, cold-formed DP or HSLA grades (HC420/780DP, HC340LA, SAPH440) avoid the energy cost and cycle time of hot stamping. The press hardening steel page covers the process trade-offs.

Surface finish: when to upgrade. Cold rolled bright (FB/FC/FD) is standard for visible or precision parts. If the part will be painted or powder coated, a hot rolled pickled surface may be sufficient at lower cost. Galvanized is required for outdoor or corrosive environments; specify coating weight (e.g. Z100, Z275) based on the expected service life. Aluminized is needed for continuous operating temperatures above 400°C, such as exhaust components. For medical or food-contact parts, specify a polished surface and request passivation or electropolishing as a secondary operation.

Grade inventory data. The grade names, spec ranges and surface conditions displayed in each result card are extracted from the HS-FINEB product inventory database (1,704 stock records, 357 unique grades). The selector uses a curated subset of 94 representative grades covering all major steel families. Spec ranges are shown exactly as recorded in inventory — they may include thickness × width × coil format notation (e.g. "0.05–6.0×20–350×C") or single-value entries. Where the inventory record has no spec range, the field is left blank rather than estimated.

Application recommendations. The application industry tags assigned to each grade are based on grade family characteristics and common industry usage patterns. For example, all electrical steel grades are tagged Electrical & Electronics and Automotive (for EV motor cores); all spring steel grades are tagged Automotive, Hardware & Fasteners and Tooling & Cutting. These tags are starting points for grade selection, not a guarantee of suitability for a specific part design. A grade may work in an industry not listed, and a listed industry may require a grade not shown depending on the exact part requirements.

Strength and thickness categories. Strength level (low / medium / high / ultra-high) and thickness range assignments are rule-based category estimates derived from grade family characteristics, not measured mechanical properties from a specific coil. For example, electrical steel is categorized as medium strength and under 1 mm thickness because that is the typical delivery condition for the family; press hardening steel is categorized as ultra-high strength and 1–6 mm because hot stamping grades are commonly supplied in that gauge. Actual tensile strength, yield strength and elongation vary by mill, heat and processing condition. Always verify against the Mill Test Certificate (MTC) before production.

Stock status. The stock indicator (In stock / Available) reflects whether the grade appears in the active inventory database with a recorded stock quantity. Stock levels change daily — the indicator is a guide, not a real-time availability check. Confirm current stock and lead time with the sales team before placing an order.

Verification before production. Grade inventory data from HS-FINEB; application recommendations based on grade family characteristics — verify with MTC before production. The how to read a Mill Test Certificate guide explains which MTC fields to check for each grade family, and the RFQ preparation checklist helps you specify all required parameters when requesting a quote.
