A precipitation-hardened martensitic stainless steel containing 15% chromium, cobalt, molybdenum, and vanadium additions designed to achieve ultra-high strength in the hardened condition. This material combines the corrosion resistance of stainless steels with exceptional hardness and strength through carefully balanced carbon and intermetallic precipitate formation. It is used in demanding aerospace, defense, and precision tooling applications where both corrosion resistance and extreme strength are required simultaneously—notably in landing gear components, valve bodies, fasteners, and cutting tools that must resist both environmental attack and severe mechanical loading.
