Forging heat treatment purposes
May 07, 2018

Forging heat treatment can be divided into two groups according to the purpose of heat treatment.

In the first group, the purpose of the heat treatment of the forgings is to provide good cutting performance for the metal cutting process and also to prepare the microstructure for the second heat treatment. The forgings belonging to this group are usually made of carburized steel, bearing steel, and tool steel.

The second group, the aim of the heat treatment of the forgings is to obtain the proper organization and achieve the technical requirements of the products. And on the premise of guaranteeing the technical requirements of the parts, moderate hardness and small hardness deviation should be obtained in order to obtain economical processing performance on metal cutting machine tools. Forgings are not subjected to final heat treatment after machining. The group of forgings are generally made of medium carbon steel and medium carbon alloy steel. Forging heat treatment common processes are annealing (including complete annealing, isothermal annealing, spheroidizing annealing and other types of annealing), normalizing (including normalizing and high temperature tempering), tempering (quenching plus high temperature tempering) and so on.
