17-4PH Stainless Steel H1150
Verifiedmetal17-4PH H1150 is a precipitation-hardened martensitic stainless steel (17% Cr, 4% Ni, Cu-strengthened) designed for high-strength aerospace and defense applications requiring corrosion resistance up to ~300°C. The H1150 condition (solution-treated and aged at 1150°F) provides ultrahigh yield strength (typically 1310 MPa) with moderate elongation, making it suitable for critical fasteners, shafts, and structural components in gas turbines and aircraft engines.

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.
