Stainless Steel 420 round bar is basically a version of 410 with higher carbon that can be easily hardened using temper-and-quench heat treatment. It contains 12 % chromium that gives off corrosion resistance properties. In the annealed condition, it shows good ductility and is capable of hardening to the highest hardness. The corrosion resistance can be easily achieved when it got hardened as well as the polished surface ground.

The round bars maintain decent strength to 1800 degree F and has great oxidation resistance. Through tight composition, the general corrosion property is maintained. The mechanical property might differ that help in obtaining a cold working. They cannot be heat treated. The finish could be BA finish, Round turned, bright polished, black and matt finish.

The carbon content is modified and has low carbon with addition of columbium and titanium with minimized austenite formation. It can be used perfectly at cryogenic temperature and excellent toughness and low magnetic permeability. The bar remains ductile and soft with rapid cooling above the peak temperature. It is low hardening so as to prevent from cracking and can be exposed as well welded at the critical temperature. The round bars has enhanced strengthens and pitting resistance in highest temperature services.

The final hardening can be achieved by fabrication as well as heat treatment. Grade 420 exhibits good resistance to the atmosphere, fresh water, mild alkalies, and foods. With the appropriate surface finish, tolerance, and dimension, it can be easily cold drawn. They are typically being used in a surgical instrument, valve cones, pump components, and shafts and axles. The round bar can be manufactured in a different finish, length, dimensions, specification, length, and forms.
