420 stainless steel is a kind of martensiform stainless steel, with certain wear resistance and corrosion resistance, higher hardness characteristics, suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, etc. Grade 420 stainless steel is a type of stainless steel that high carbon content and low in chromium content. The chromium in this stainless steel can be as low as 12%. Just like other grades of steel, grade 420 stainless steel can also be hardened through various methods such as heat treatment. Type 420 stainless steel heat treatment includes annealing, hardening, tempering and stress relief. Preparation for heat treatment includes precleaning, preheating, atmosphere protection, salt bath, and hydrogen embrittlement.
Precleaning: All workpieces of SS420 and fixtures must be thoroughly cleaned, such as oil, sweat and other stains on the surface of the workpiece. Preheating: The thermal conductivity of type 420 stainless steel is usually lower than that of carbon steel. When heating rapidly, the workpiece is easily deformed and cracked. Therefore, preheating is recommended. The preheating temperature is generally 760-790 °C (1400-1450 °F). Heavy-duty parts can be preheated in two stages: Preheat at 540 °C (1000 °F) firstly, and then heat to 790 °C (1450 °F).
Atmosphere protection: Austenitizing temperature 1010 °C (1850 °F), dew-point temperature: 10-12 °C (50-54 °F) for AISI 420 wrought martensitic stainless steel.
