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.
