15Cr Martensitic Stainless (var. 11)

metal

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.

Quality & Standards

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
