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.
WebIntroduction. 420 Stainless Steel is a martensitic stainless steel with 12% Chromium which is sufficient to give good corrosive resistance properties. It’s best corrosive resistance is when hardened and surface is ground or polished.It has good ductility in the annealed condition but can be hardened up to 500HB (highest of the chromium grades). WebAISI 420 steel (SS420) is very brittle under just hardened conditions and usually must be tempered to achieve useful toughness. The tempering temperature for 420 grade …
