Choose 20# material filter cover, processing technology has cold finishing, The forging process of the product is essential to heat treatment, one of the procedures is annealing, is to heat the steel whose organization deviates from the equilibrium state to the appropriate temperature, heat preservation to a certain time, and then slowly cooling (with the furnace cooling), to obtain the heat treatment process of close to the equilibrium state of the organization.

There are many kinds of steel annealing process, according to the heating temperature can be divided into two categories: one is at the critical temperature (Ac1 or Ac3) above the annealing, also known as phase change recrystallization annealing, including complete annealing, incomplete annealing, spheroidizing annealing and diffusion annealing (homogenization annealing).

The other is annealing below the critical temperature, including recrystallization annealing and stress relief annealing. According to the cooling mode, annealing can be divided into isothermal annealing and continuous cooling annealing.
