420 stainless steel is widely used in the medical and cutlery industries. It is suitable for applications such as instruments, knives, hand tools, pump shafts and plastic moulds. SS420 is not recommended for use in temperatures above the relevant tempering temperature, because of the reduction in mechanical properties.
Best corrosion resistance of 420 stainless steel is achieved when SUS420 is hardened and surface ground or polished. In the hardened condition SUS420 has good corrosion resistance to atmosphere, foods, fresh water, mild alkalis and acids, steam, crude oil and other similar corrosive media.
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each 420 stainless steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of stainless steel 420 grade.

Welding of stainless steel grade 420J2 is easy. It is recommended that welding in annealed or hardened and tempered conditions should be avoided as it causes formation of brittleness, resulting in cold cracking due to contraction stresses.
Pre-heating and inter-pass temperature control during welding, followed by very slow cooling and post-weld annealing are good measures to take to prevent cracking.
Stainless steel grade 420J2 is inexpensive and highly corrosion resistant steel. Stainless steel grade 420J2 is known to possess good strength and reasonable impact resistant properties in hardened and tempered conditions when compared with 440 grades.
420j2 stainless steel contains medium quality carbon content. It has good corrosion resistance in salt-free atmospheres and in most industrial environments. It is resistant to many chemicals and household cleaners; and, it is also a more durable steel compared to the 440 grades.
