Aisi 420 Stainless Steel Heat Treatment

Like any other martensitic stainless steel grade 420 can also be hardened by heat treatment to enhance mechanical properties.

Aisi 420 stainless steel heat treatment.

It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished surface grounded or hardened. Speci cally the caps that hold the shaving blades. The results obtained in this investigation of aisi 420 stainless. The cycle control of heat treatments on the quenching and tempering operation of aisi 420 stainless steel is essential for improved material performance.

Martensitic stainless steel 6 1. 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. This material is used in mechanical engineering and power. The strength of 1 4021 depends on the tempering temperature.

Aisi 420 x20cr13 1 4021 can be hardened by holding the temperature between 950 c and 1050 c with a subsequent cooling in air oil or polymer. This research focuses on the aisi 420 type martensitic stainless steel. Heat treatment of aisi 420 grade martensitic stainless steel a. X20cr13 is usually divided in two heat treatment conditions qt700 and qt800.

The influence of the heat treatment on the corrosion resistance of the martensitic stainless steel type aisi 420 was discussed. Ss420 datasheet the tables below give 420 stainless steel ss420 datasheet and specification including chemical composition properties heat treatment etc. Du to its balance between workability and corrosion resistance philips is using this stainless steel for their shavers. It was shown that the corrosion resistance was strongly influenced.

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. The adequate choice of heat treatment parameters can lead an optimization on its mechanical properties and corrosion resistance. This material con tains a relative low carbon and chromium concentration 0 32 and 13 7 respectively. Grade 420 stainless steel is a high carbon steel with a minimum chromium content of 12.

Like any other stainless steel grade 420 can also be hardened through heat treatment.
