Product Description

Product Description

420J1 stainless steel

420J1 stainless steel is a martensitic stainless steel belonging to the 400-series stainless steels. It contains approximately 12–14% chromium and a relatively low carbon content, which provides good corrosion resistance, good toughness, and moderate hardness after heat treatment.

DSM Steel specializes in manufacturing precision cold-rolled stainless steel strip and coil. We provide custom processing services including precision slitting, heat treatment, edge finishing, and strict dimensional tolerance control to meet the requirements of different industries.

Whether you require stainless steel for cutlery, industrial blades, medical devices, or precision engineering applications, DSM Steel can provide consistent quality, competitive pricing, and stable global supply.
