ASTM 420J1 stainless steel plate Specification

ASTM 420J1 stainless steel plate is a higher carbon version of 410; like most non-stainless  steels it can be hardened by heat treatment. ASTM 420J1 stainless steel plate contains a minimum of 12 per cent chromium, just sufficient to give corrosion resistance properties.Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished.

ASTM 420J1 stainless steel plate applies to construction field,ships building industry,petroleum,war and electricity industries, food processing and medical industry,boiler heat exchanger, machinery and hardware fields.
