17-4PH Stainless Steel H1100
Verifiedmetal17-4PH (precipitation-hardened stainless steel) in H1100 condition is a martensitic stainless steel strengthened by copper and niobium precipitation, offering yield strength around 1,310 MPa with good corrosion resistance and toughness, used extensively in aerospace applications including fasteners, shafts, and structural components. The H1100 temper provides a balance of high strength and ductility through controlled aging after solution treatment and cold work.

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.
