7.Heat treatment guarantees quality

  Metallic materials consist of a microstructure of small crystals called "grains" or crystallites.

The nature of the grains (i.e. grain size and composition) is one of the most effective factors

that can determine the overall mechanical behavior of the metal. Heat treatment provides

an efficient way to manipulate the properties of the metal by controlling the rate of diffusion 

and the rate of cooling within the microstructure. In the R & D practice, Dongfang invents 

Application Method for Warm Period Timing Quenching in Grinding Materials Heat Treatment 

and other skills. Machine oil is used to quench, making workpiece heated evenly, promoting 

the first formed carbide decompose once again and then forming uniformly distributed reticular 

carbides in the matrix. Hardness gap between center and surface is less than 1.5 HRC.
