0.05C 8.5Cr-1.9Mo-9.8Ni Low Alloy Steel
metalThis is a precipitation-hardening martensitic stainless steel with high chromium (8.5%), nickel (9.8%), and molybdenum (1.9%) content, designed to achieve high strength through age-hardening heat treatment while maintaining corrosion resistance and toughness. It is primarily used in aerospace and defense applications requiring combination of high strength, fatigue resistance, and resistance to stress-corrosion cracking in moderately aggressive environments. The high nickel and molybdenum content distinguish this alloy from conventional martensitic stainless steels, enabling better fracture toughness and environmental resistance at elevated strength levels compared to lower-alloy grades.
