17-4PH Stainless Steel H1150Ma
Verifiedmetal17-4PH stainless steel is a precipitation-hardening martensitic stainless steel (Fe-Cr-Ni-Cu-Nb) offering high strength and corrosion resistance, widely used in aerospace and defense applications including fasteners, shafts, and structural components. The H1150Ma condition is solution-annealed at 1150°F and aged to provide optimized strength-ductility balance with good fracture toughness for critical forged, tubed, and ring components per AMS 5643.

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.
