 420 Stainless Steel Plate

420 Stainless Steel Plate

420 is a hardenable martensitic stainless steel that contains at least 12% chromium, just enough to provide corrosion resistance. It has good ductility in the annealed condition, but can be hardened to a minimum Rockwell hardness of 50 HRC, the highest hardness in the 12% chromium grade.
