Aisi 420 Stainless Steel Heat Treatment

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.

Aisi 420 stainless steel heat treatment.

All parts cleaned in a solvent bath to remove all traces of oil prior to heat treatment. Part placed into a vacuum furnace. Aisi 420 high carbon steel is a high carbon steel with a minimum chromium content of 12. 2h13 does not show resistance to chlorine salts and intergranular corrosion.

It is magnetic in both the annealed and hardened conditions. Heat treatment of aisi 420 grade martensitic stainless steel a. 0preheat part to 1 450 f and hold for 45 minutes. 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.

Hardening for 420 grade stainless steel. Maximum corrosion resistance is attained only in the fully hardened or fully hardened and stress relieved condition. Subcritical annealing recommended temperature for aisi. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished surface grounded or hardened.

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. Applications potential ak steel type 420 is a martensitic stainless steel that provides corrosion resistance similar to type 410 plus increased strength and hardness. Annealing for astm aisi 420 wrought stainless steel. Like any other stainless steel aisi 420 can also be hardened through heat treatment.

Parts are heated to 1 8500f and held for 1 hour. 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. Currently our sponsor s heat treating process for the 420 stainless steel product is listed below.
