A precipitation-hardened martensitic stainless steel enhanced with cobalt, molybdenum, vanadium, and nitrogen to achieve high strength and hardness in the hardened condition. This composition represents a specialty variant designed for applications demanding exceptional strength-to-weight performance while maintaining corrosion resistance typical of 16% chromium martensitic grades. Commonly encountered in aerospace fasteners, landing gear components, and high-performance mechanical systems where the combination of hardness, fatigue resistance, and modest ductility meets design requirements for reliability under cyclic and impact loading.
