A carbon-rich 16% chromium martensitic stainless steel heavily alloyed with cobalt (12.8%), molybdenum, and vanadium, designed to achieve exceptional hardness and wear resistance through martensitic strengthening and carbide precipitation. This variant is used in precision cutting tools, dies, and high-wear applications where stainless corrosion resistance must be combined with extreme hardness; the high carbon and cobalt content distinguish it from conventional 420/440 martensitic grades, positioning it for demanding aerospace, medical device, and tooling environments where both corrosion protection and abrasion resistance are critical.
