![]() It is not usually used at temperatures exceeding 800 oF (427 oC) due to quick hardening and loss of corrosion resistance. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished.Īlloy 420 is used for a variety of applications where good corrosion and outstanding hardness is necessary. Corrosion resistance is lower than the common austenitic grades and their useful operating range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures. Martensitic stainless steels are designed for high hardness and sometimes other properties are to some degree compromised. Due to its hardening properties, Alloy 420 is not often welded, although it is possible. It has good ductility it the annealed condition but is capable of being hardened to a minimum Rockwell hardness of 50 HRC, the highest hardness of the 12% chromium grades.

Alloy 420 has higher carbon content than Alloy 410 which is designed to optimize strength and hardness characteristics. Similar to 410, it contains a minimum of 12% chromium, just sufficient enough to give corrosion resistant properties. Alloy 420 is a hardenable, martensitic stainless steel that is a modification of Alloy 410. ![]()
