Annealing for ASTM AISI 420 wrought stainless steel.
Hardening for 420 grade stainless steel: Heating to austenitizing temperature 980-1065 °C (1800-1950 °F), quenching medium is air or oil, if the part thickness is > 0.25 in. (6.4 mm), oil quenching should be used. After quenching to room temperature, immediate cold treatment is recommended and the recommended cold treatment temperature is -75±10 °C (-100±20 °F), which can reduce austenite and keep maximum dimensional stability.
