8.Unique heat treatment process
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.
