0.14C 8.1Cr-1.8Mo-11.6Ni Low Alloy Steel

This 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.
