A high-carbon martensitic stainless steel (≈16% Cr) strengthened by significant vanadium, molybdenum, and cobalt additions, designed for applications demanding both corrosion resistance and extreme hardness. This composition—with nearly 1% carbon and substantial interstitial strengtheners—represents a premium tool steel variant positioned between conventional martensitic stainless steels and cobalt-hardened high-speed steels, offering superior wear resistance and edge retention compared to lower-carbon martensitic grades. Industrial adoption focuses on precision cutting tools, gauges, and wear-critical components in aerospace and manufacturing where corrosion resistance cannot be sacrificed for performance.
