Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.JS777 is a high-alloy, fully austenitic stainless steel developed for applications where corrosive conditions are too severe for the standard grades of stainless steel. It also provides a cost-effective alternative to more expensive nickel-base and titanium-base alloys. The combination of chromium, nickel and molybdenum in JS777 give it a high degree of resistance to stress-corrosion cracking. It also has a relatively low carbon content and a columbium addition to tie up the remaining carbon to guard against intergranular corrosion because of carbide precipitation (sensitization). Copper is added to JS777 to improve markedly its resistance to general corrosion in strongly acid environments.
