15Cr Martensitic Stainless (var. 4)
metalA cobalt-strengthened martensitic stainless steel with ~15% chromium and elevated carbon content, designed to achieve high hardness and wear resistance through martensitic transformation and precipitation hardening. This variant is typically used in demanding applications requiring superior edge retention and fatigue strength, where corrosion resistance must be balanced with extreme mechanical performance—such as high-speed cutting tools, specialized valve components, and aerospace fasteners operating under cyclic loading.
