17-4PH Stainless Steel a
Verifiedmetal17-4PH is a chromium-nickel-copper precipitation-hardening stainless steel offering high strength (up to 1310 MPa yield) and good corrosion resistance, commonly used in aerospace engine components, fasteners, and pump impellers. The "a" condition (as-cast from investment casting per AMS 5344) provides the baseline mechanical properties prior to age hardening, with moderate strength and ductility suitable for subsequent heat treatment to achieve desired strength levels.

Environmental
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.
