Representative grades consolidated from 1,700+ Baosteel-supply listings for range planning — availability, gauge, coil weight and lead time confirmed per RFQ. Equivalents are indicative; chemistry confirmed on the MTC of each delivery.

Processing before dispatch

Buy material — or material already processed

Every process below runs in-house in Shanghai, so tolerances are documented, not promised.

Precision Cold Rolling

Gauge tolerance and surface finish to your die's window.

Spheroidizing Annealing

Carbide conditioning for clean fine blanking and forming.

Heat Treatment

Hardening, tempering, stress relief — documented.

Precision Slitting

Narrow coil widths with managed burr and camber.

Cut-to-Length & Leveling

Flat sheets and blanks for feeders and laser.

Custom OEM Processing

Packing, edging, interleave, labeling for your line.

Straight answers

Range questions buyers ask first

Do you stock all these grades, or are some on order?
Core grades — the ones this site highlights — are held as ready stock in Shanghai in coil form. The full Baosteel grade range is available on confirmed lead time. Availability is confirmed at RFQ for every grade, gauge and quantity.
Can you supply grades to my European or Japanese standard?
Yes. Send your standard and grade (EN, JIS, DIN, ASTM) and we map it to the closest Baosteel equivalent with a side-by-side chemistry comparison before you commit — no substitution surprises later.
What forms can you deliver — coil, sheet or slit strip?
All three. Coil for progressive dies, sheets and blanks for stamping and laser feeders, and slit strip in narrow widths with managed burr. Specify your feeder or die at RFQ and we quote the right form.
Do you supply press hardening steel with Al-Si coating for hot stamping?
Yes — 22MnB5+AS, Usibor1500P, T1500P-SVW, AC and SABC series, CR*HS+AS grades and TA custom grades, supplied with mill certificate and coating weight documentation. Hot-forming trials and sample coils can be arranged.
What documentation ships with each delivery?
A Mill Test Certificate with chemistry, mechanicals and processing history on every coil, plus the original mill quality certificate from the Baosteel supply chain. Third-party inspection and special test reports on request.
