Description
Stainless Steel 420
Grade 420 stainless steel is a high carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened. This grade has the highest hardness 50 HRC among all the stainless steel grades with 12% chromium.
