11Cr-7Ni-1.6Mo Stainless

metal

This 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.

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.
