JIS G4305 SUS410L Steel Plate | 410L BA/2B Stainless Steel
What is JIS G4305 SUS410L Steel Plate?
As a professional stainless steel supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present JIS G4305 SUS410L Steel Plate (also known as 410L stainless steel).
SUS410L is a low-carbon ferritic stainless steel under the Japanese standard JIS G4305 for cold-rolled stainless steel plates, sheets and strips. With a chromium content of approximately 11.5–14.5% and very low carbon (≤ 0.03%), it offers better weldability, improved resistance to intergranular corrosion and better toughness than standard martensitic 410. It is fully magnetic, has good formability and provides moderate corrosion resistance in mild environments. The most common surface finishes are 2B and BA.
SHH STEEL supplies SUS410L 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 0.3 mm to 3.0 mm (thicker plates available on request), widths up to 1500 mm, in coil or cut-to-length form. All materials are delivered with full Mill Test Certificates.
Material Specification

Chemical Composition
Chemical composition according to JIS G4305 (Heat Analysis):
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.030 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 1.00 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 11.50 – 14.50 |
| Nickel (Ni) | ≤ 0.60 |
Note: The very low carbon content is the key feature that improves weldability and reduces the risk of intergranular corrosion compared with standard 410.
