0.05C 5.3Cr-1.7Mo-11.1Ni Low Alloy Steel

metal

This is a nickel-chromium-molybdenum low-alloy steel with controlled carbon content, designed for high-strength structural and aerospace applications where good toughness and corrosion resistance are required simultaneously. The composition—particularly the 11% nickel, 5% chromium, and molybdenum addition—is characteristic of aerospace-grade steels used in landing gear, fasteners, and critical forgings that must withstand both high stresses and harsh operating environments. Engineers select this alloy family over carbon steels when fracture toughness and fatigue resistance are as critical as strength, and it competes with precipitation-hardened stainless steels and nickel-based superalloys in weight-sensitive, cost-conscious applications.

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.
