JIS G4305 SUS410S Steel Plate | 410S Stainless Steel
General Description
As a professional stainless steel supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present JIS G4305 SUS410S Steel Plate (also known as 410S stainless steel).
SUS410S is a low-carbon version of the 12% chromium stainless steel under the Japanese standard JIS G4305 for cold-rolled stainless steel plates, sheets and strips. By limiting the carbon content, SUS410S offers significantly better weldability and reduced risk of hardening or cracking after welding compared with standard SUS410. It provides moderate corrosion resistance in mild environments, good formability and is fully magnetic. This grade is widely used as a cost-effective alternative where welding is required and high hardness is not the primary need.
SHH STEEL supplies SUS410S as Mill Direct Supply, sourcing directly from major Chinese stainless steel mills. This ensures competitive mill pricing, consistent quality, shorter lead times and full traceability. We offer thicknesses from 0.4 mm to 6.0 mm, widths up to 1500 mm, in coil or cut-to-length form. All materials are delivered with full Mill Test Certificates.

Chemical Composition
Chemical composition according to JIS G4305 (Heat Analysis):
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 1.00 |
