10Cr-10Ni-1.9Mo Stainless

metal

10Cr-10Ni-1.9Mo is a precipitation-hardened martensitic stainless steel combining moderate chromium and nickel content with molybdenum and trace titanium and aluminum additions to enable age-hardening strengthening. This alloy targets applications requiring a balance of corrosion resistance, high strength, and reasonable toughness—particularly in aerospace, defense, and oil & gas sectors where both environmental protection and structural performance are critical. The composition suggests optimization for elevated-temperature service or corrosive marine environments, with the molybdenum addition improving pitting resistance and the precipitation-hardening elements (Ti, Al) providing strength without sacrificing machinability compared to fully austenitic stainless alternatives.

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.
