Aisi 420 stainless steel heat treatment.

Heat treatment of aisi 420 grade martensitic stainless steel a. Maximum corrosion resistance is attained only in the fully hardened or fully hardened and stress relieved condition. Heating to austenitizing temperature 980 1065 c 1800 1950 f. 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. 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. Like any other stainless steel aisi 420 can also be hardened through heat treatment. Type 420 stainless steel heat treatment annealing.

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. Annealing for astm aisi 420 wrought stainless steel. It is magnetic in both the annealed and hardened conditions. Currently our sponsor s heat treating process for the 420 stainless steel product is listed below.

It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished surface grounded or hardened. Part placed into a vacuum furnace. Applications potential ak steel type 420 is a martensitic stainless steel that provides corrosion resistance similar to type 410 plus increased strength and hardness. Process anneal grade 420 can be annealed at 735 to 785 c and air cooled.

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. Subcritical annealing recommended temperature for aisi.
