11Cr-7Ni-1.6Mo Stainless
metalThis is a martensitic stainless steel alloyed with cobalt and tungsten, formulated to achieve high hardness and strength at elevated temperatures while maintaining corrosion resistance typical of chromium stainless alloys. The material is used primarily in aerospace and power generation applications where components must withstand extreme thermal and mechanical loads, such as turbine blades, valve seats, and high-temperature fasteners. Its cobalt-tungsten addition strengthens the steel matrix for demanding high-temperature service, making it an alternative to nickel-based superalloys when ferrous metallurgy and lower material costs are preferred.
