8.1Cr-1.9Mo-10.1Ni Low Alloy Steel
metalAn ultra-high-strength low-alloy steel combining significant chromium (8.1%), molybdenum (1.9%), and nickel (10.1%) content to achieve excellent hardenability, fatigue resistance, and corrosion resistance in a martensitic matrix structure. This composition is typical of premium aerospace and defense alloy steels, particularly those specified for highly stressed components requiring both strength and damage tolerance in demanding environments.

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.
