0.05C 5.3Cr-1.8Mo-11.6Ni Low Alloy Steel
metalThis is a low-alloy steel with a complex alloying scheme combining chromium, molybdenum, and nickel to achieve high strength and corrosion resistance in a relatively lean carbon matrix. It is typically used in aerospace and defense applications, particularly for landing gear components, fasteners, and structural parts that require excellent fatigue resistance and resistance to hydrogen embrittlement in high-strength applications. Engineers would select this material over conventional high-carbon or fully austenitic stainless steels when demanding both very high strength and toughness in moderately corrosive environments, along with improved machinability compared to martensitic stainless alternatives.

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.
