The wear resistance of AISI 420 stainless steel was also improved evidently by plasma nitriding. These results showed that plasma nitriding AISI 420 stainless steel at anodic potential (ground 0 V) provides an alternative process to increase the surface hardness, wear resistance as well as the corrosion properties with no evident edge-effect.
Decarburization deteriorates the surface mechanical properties of steel. It refers to the loss of carbon from steel's surface when exposed to an open-air environment in elevated-temperature conditions. Despite the short interaction time and fast thermal cycle of the laser surface-hardening process, decarburization may still occur. This paper …

AISI 420 steel (SS420) is very brittle under just hardened conditions and usually must be tempered to achieve useful toughness. The tempering temperature for 420 grade stainless steel after austenitizing: 205-370 °C (400-700 °F). The corresponding tensile strength and Rockwell hardness are 1550-1930 MPa (225-280 ksi) and 48-56 HRC.
AISI 420 is a low-chromium member of the martensitic family of stainless steels and is commercially available in a low-carbon version (with a specified carbon content of less than 0.15%), and a medium-carbon version (with a maximum carbon content of 0.5%). In the hardened and tempered condition, medium-carbon AISI 420 has high …
