1: Brief Introduction Of 420 stainless steel  

Alloy 420 is a hardenable, martensitic stainless steel that is a modification of Alloy 410. Similar to 410, it contains a
minimum of 12% chromium, just sufficient enough to give corrosion resistant properties. Alloy 420 has higher carbon content
than Alloy 410 which is designed to optimize strength and hardness characteristics. It has good ductility it the annealed
condition but is capable of being hardened up to Rockwell hardness 50 HRC, the highest hardness of the 12% chromium
grades. Due to its hardening properties, Alloy 420 is not often welded, although it is possible. Martensitic stainless steels
are designed for high hardness and sometimes other properties are to some degree compromised. 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. Its best corrosion resistance is achieved
when the metal is hardened and surface ground or polished.
Corrosion Resistance:
*Less resistant than the austenitic grades and the 17% chromium ferritic alloys
*Good resistance in the hardened condition to the atmosphere, foods, fresh water, and mild acids
*Resistance lowered in the annealed condition
*Best with a smooth surface finish
Heat Resistance:
*Not recommended for use above the relevant tempering temperature because of reduction in mechanical properties
*Scaling temperature is approximately 1202oF (650oC)
