420 stainless steel contains a minimum of 12 percent chromium, sufficient to give 420 corrosion resistance properties. It has good ductility in the annealed condition but is capable of being hardened up to 50 RHC.

Its best corrosion resistance is achieved when 420 is hardened and surface ground or polished. In the hardened condition, 420 has good corrosion resistance to the atmosphere, foods, fresh water, mild alkalies and acids, steam, sterilizing solutions, crude oil, gasoline, and other similar corrosive media.
