0.14C 8.1Cr-1.8Mo-11.6Ni Low Alloy Steel
metalThis is a high-nickel, chromium-molybdenum low-alloy steel designed for applications requiring a combination of high strength and corrosion resistance. The composition—roughly 11.6% Ni, 8.1% Cr, and 1.8% Mo with minimal carbon (0.14%)—positions it in the maraging or precipitation-hardening steel family, where strength is developed through heat treatment rather than carbon content alone. It is primarily used in aerospace, defense, and high-performance engineering applications where components must withstand demanding mechanical loads in corrosive or thermal environments while maintaining dimensional stability and fracture toughness.

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.
