15Cr Martensitic Stainless (var. 3)
metalA high-carbon, cobalt-strengthened 15% chromium martensitic stainless steel with deliberate additions of molybdenum, vanadium, and nitrogen for enhanced hardness and wear resistance. This variant occupies the intersection of stainless corrosion resistance and tool steel performance, making it suitable for demanding applications requiring both environmental durability and extreme hardness. The elevated carbon content and secondary hardening elements position it for specialized use cases where conventional martensitic stainless steels (like 440C or 12Cr) prove insufficient in edge retention or abrasive resistance.
