420 Stainless Steel Pipe is a martensitic chromium stainless steel designed for a useful combination of hardness, strength, wear resistance, and moderate corrosion resistance. Its properties can be significantly increased through quenching and tempering. 420 is suitable for valve components, pump parts, shafts, mechanical tubing, tools, and wear-resistant components where higher hardness is required than conventional ferritic or austenitic stainless steels.
