Alloy 420 is a hardenable, martensitic stainless steel that is a variation of Alloy 410. Parallel to 410, it contains a least of 12% chromium, just enough to give corrosion tough properties. Alloy 420 has advanced carbon content than Alloy 410 which is calculated to enhance strength and hardness features. It has good ductility in the hardened condition but is accomplished of being hardened up to Rockwell hardness 50 HRC, the highest hardness of the 12% chromium grades. Due to its hardening assets, Alloy 420 is not frequently welded, though it is possible. Martensitic stainless steels are deliberate for high hardness and sometimes other properties are to some degree negotiated.
Corrosion resistance is lower than the common austenitic grades and their useful working range is limited by their loss of ductility at sub-zero temperatures when the metal is and loss of strength by over-tempering at raised temperatures. Its best corrosion resistance is realized hardened and surface ground or polished.
