Square Round 430 631 Stainless Steel Bar
The listing offers square and round bars made from stainless‑steel grades 430 (AISI 430) and 631 (UNS S17400). Both grades are ferritic and precipitation‑hardening respectively, providing corrosion resistance and strength. Bar diameters are supplied from 2 mm up to 500 mm, with lengths cut to the buyer’s specification. Available surface conditions include black, pickled and bright finishes.
Grade 430 is a cost‑effective ferritic grade commonly used where moderate corrosion resistance is required, while 631 is a 17‑7PH precipitation‑hardening alloy valued for high‑strength applications. The free‑cutting composition of these steels facilitates high‑speed machining, a standard expectation for precision component manufacturers. Typical industry practice calls for compliance with ASTM A276, GB/T 1220 and JIS G4303 for chemical composition and mechanical properties. Standard tolerances for diameter are ±0.2 mm for sizes under 50 mm and ±0.5 mm for larger sections, which aligns with normal machining allowances.
Buyers such as equipment builders, automotive part makers and architectural hardware fabricators rely on these bars for shafts, brackets and structural inserts. The supplier ships from Shanghai under FOB terms, with standard export packing and payment by L/C sight or T.T against B/L. Lead time is quoted as 20‑30 days after receipt of down‑payment, and the exact MOQ must be confirmed directly with the supplier.

Sourcing Square Round 430 631 Stainless Steel Bar from Jiangsu Steel Group Co., Ltd. - China Import Guide
Before placing an order, confirm the grade and corresponding mill test certificate, verify the surface finish required for your machining process and check that the supplied tolerances meet your design limits. Ask the supplier to provide the latest chemical analysis and tensile test reports for the specific heat you will receive. Clarify any special dimensional or length requirements early to avoid re‑work later.
The supplier ships from Shanghai under FOB terms, with a quoted lead time of 20‑30 days after receipt of down‑payment. Buyers should confirm whether the shipment will be organised as FOB Shanghai or CIF to a specific discharging port, and agree on the incoterm that best fits their logistics chain. Accepted payment methods are L/C sight or T.T against a copy of the bill of lading, which should be verified before dispatch.
Arrange a third‑party inspection or request a pre‑shipment quality audit to validate compliance with ASTM A276 and the agreed specifications. Obtain the mill test certificate, surface finish report and any corrosion test results before the goods leave the factory. Ensure that all customs documentation, including the commercial invoice and packing list, matches the agreed product description and quantities.
