What Is Stainless Steel?
Martensitic stainless steels were the first stainless steels that were commercially developed (as cutlery) and have a relatively high carbon content (0.1% - 1.2%) compared to other stainless steels. They are plain chromium steels containing between 12% and 18% chromium. Alloy 410 is the basic, general purpose, and magnetic grade that is hardenable by quenching and tempering. These stainless steels can be heat treated to obtain high strength with good ductility.
