420 cold-rolled stainless steel sheet is a high-carbon martensitic stainless steel produced through precision cold rolling processes. The cold rolling operation imparts superior surface finish, tight dimensional tolerances, and enhanced mechanical properties compared to hot-rolled equivalents. This grade offers high hardness (after heat treatment), good wear resistance, and moderate corrosion resistance. It is widely used in applications requiring a combination of sharp
