13Cr Martensitic Stainless (var. 8)
metal13Cr martensitic stainless steel is a chromium-based iron alloy strengthened through martensitic transformation and precipitation hardening via cobalt and molybdenum additions. This variant exhibits an unusually high carbon content (0.925%) combined with cobalt alloying (14.3%), positioning it for demanding applications requiring exceptional hardness and wear resistance alongside corrosion protection. It competes with premium tool steels and specialty stainless grades in applications where both toughness and corrosion resistance must be balanced against cost and machinability constraints.
