Aisi 420 Stainless Steel Heat Treatment

Parts are heated to 1 8500f and held for 1 hour.

Aisi 420 stainless steel heat treatment.

All parts cleaned in a solvent bath to remove all traces of oil prior to heat treatment. Heating to austenitizing temperature 980 1065 c 1800 1950 f. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished surface grounded or hardened. Hardening for 420 grade stainless steel.

Process anneal grade 420 can be annealed at 735 to 785 c and air cooled. Currently our sponsor s heat treating process for the 420 stainless steel product is listed below. X20cr13 1 4021 aisi 420 specification and application martensitic stainless steel intended for thermal improvement showing high mechanical properties strength ductility and machinability while maintaining sufficient corrosion resistance. Aisi 420 high carbon steel is a high carbon steel with a minimum chromium content of 12.

After the quenching and partitioning heat treatment the aisi 420 steel with high amounts of reversed austenite demonstrates a distinctive combination of high ductility and high ultimate tensile strength associated with deformation driven austenite to martensite transformation. Annealing grade 420 stainless steels can be heated at temperatures from 840 to 900 c followed by slow furnace cooling at 600 c and then air cooling. 2h13 does not show resistance to chlorine salts and intergranular corrosion. 0preheat part to 1 450 f and hold for 45 minutes.

Subcritical annealing recommended temperature for aisi. It is magnetic in both the annealed and hardened conditions. Type 420 stainless steel heat treatment annealing. Maximum corrosion resistance is attained only in the fully hardened or fully hardened and stress relieved condition.

Lade mukand ltd mumbai maharastra india thane india martensitic stainless steel aisi 420 grade of diameter 55mm was taken for experiment to study the mechanical and microstructure properties of the steel in hardened and tempered condition. Like any other stainless steel aisi 420 can also be hardened through heat treatment. Part placed into a vacuum furnace.
