17-7PH Stainless Steel
VerifiedmetalUNS S17700· AISI 631
17-7PH is a precipitation-hardening martensitic stainless steel (17% Cr, 7% Ni) designed for high-strength aerospace applications requiring excellent corrosion resistance and fatigue performance up to approximately 600°C. H1050 and STA (solution-treated and aged) conditions provide yield strengths in the 1200-1450 MPa range with superior stress-corrosion cracking resistance compared to conventional martensitic grades.

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.
