0.05C 5.0Cr-1.8Mo-11.6Ni Low Alloy Steel

metal

This is a precipitation-hardening nickel-chromium-molybdenum low-alloy steel with controlled carbon content, aluminum, and titanium additions—composition typical of maraging or high-strength aerospace steels. It is engineered for critical structural and fastening applications requiring a combination of ultra-high strength, toughness, and corrosion resistance, particularly in demanding aerospace, defense, and offshore environments where conventional carbon steels or austenitic stainless steels are insufficient. The high nickel and chromium content provides excellent corrosion and fatigue resistance, while the molybdenum, aluminum, and titanium promote precipitation hardening during heat treatment, enabling exceptional strength-to-weight performance.

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.
