Description:
420J1 grades are hardenable martensitic stainless steel used for cutlery, pump bushings and valves
Application:
Cutlery / Pump Valves/ Bushings / Screw-drivers.
Corrosion Resistanc:
This grade has moderate corrosion resistance to atmosphere, fresh water, mild acids present in fruit juices and milk like lactic, tartaric, citric acids, mild alkalis etc.
The corrosion resistance is best in hardened and tempered conditions.
