A high-strength 13% chromium martensitic stainless steel heavily alloyed with cobalt (9.6%), molybdenum (3.6%), and nitrogen (0.12%), designed to achieve exceptional hardness and strength through martensitic hardening. This composition targets applications demanding superior wear resistance and fatigue performance in corrosive environments, positioning it between conventional 13Cr martensitic grades and premium precipitation-hardened stainless steels. The cobalt and molybdenum additions enhance strength and toughness simultaneously, making it suitable for demanding aerospace, power generation, and oil & gas components where both corrosion resistance and structural integrity under load are critical.
