AerMet 100 Steel STA
VerifiedmetalAerMet 100 is a high-strength martensitic steel alloyed with cobalt, nickel, molybdenum, and chromium, designed for critical aerospace structural and fastener applications requiring exceptional strength-to-weight ratios at service temperatures to 350°F. The STA condition (solution treated and aged) achieves ultimate tensile strengths of ~280 ksi with good fracture toughness and fatigue resistance, making it suitable for landing gear, airframe fittings, and high-performance fasteners in military aircraft.

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.
