AISI 8630 Alloy Steel
metal· 8630· AISI 8630
AISI 8630 is a nickel-chromium-molybdenum alloy steel (0.28–0.33% C, 0.55–0.75% Ni, 0.40–0.60% Cr, 0.15–0.25% Mo) used primarily in aerospace applications for landing gear, fasteners, and highly stressed structural components requiring high strength and fatigue resistance. The alloy provides yield strengths in the range of 180–280 ksi depending on heat treatment and section size, with good toughness and moderate hardenability suitable for medium-section forgings and bars.

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.
