AISI Grade 420 stainless steel is a higher carbon version of 410; like most non-stainless steels it can be hardened by heat treatment. It contains a minimum of 12 per cent chromium, just sufficient to give corrosion resistance properties. It has good ductility in the annealed condition but is capable of being hardened up to Rockwell Hardness 50HRC, the highest hardness of the 12 per cent chromium grades. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished.
AISI 420 grade stainless steel has many advantages, such as,
Corrosion Resistance
Heat Resistance
Welding
Machining
AISI 420 grade stainless steel is widely used in Cutlery, Knife Blades, Surgical Instruments, Needle Valves, Shear Blades and on.
