AM-355 Stainless Steel T850

Verifiedmetal

AM-355 stainless steel is a martensitic stainless alloy (13% Cr, 4.7% Ni, 2.7% Mo) used in aerospace applications requiring high strength and corrosion resistance at elevated temperatures. The T850 temper (solution heat-treated and age-hardened) provides yield strengths in the 1380–1520 MPa range with good bearing strength and moderate ductility, suitable for critical fasteners, compressor components, and high-stress structural applications to approximately 315°C.

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.
