0.05C 5.2Cr-1.8Mo-11.7Ni Low Alloy Steel

metal

This is a precipitation-hardened nickel-chromium-molybdenum low-alloy steel, strengthened by aluminum and titanium additions that form intermetallic phases (likely γ″ Ni₃Al). The high nickel content (~12%) combined with chromium and molybdenum provides excellent corrosion resistance and thermal fatigue resistance, positioning it as a high-strength, corrosion-resistant material suitable for demanding aerospace and oil & gas applications. Engineers select this alloy over conventional steels or stainless grades when superior strength-to-weight ratio, environmental cracking resistance, and thermal cycling durability are critical—typical in landing gear, fasteners, pump shafts, and subsea equipment exposed to corrosive or cyclic thermal stress.

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.
