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.
