1.Physical properties

2.Chemical composition as follow

3.Picture of the high chromium alloy cast grinding media

4. Advanced heat treating process

     Heat treatment is the key step of the whole  production process.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.

    Due to the unique heat treatment process, grinding medias obtain the required hardness and metallurgical 

  structure,and the hardness gap between core and surface  is less than 1.5 HRC.

5.Optimized Production Process

    Dongfang Production Process is based on times of trials, we adhere to ensure the quality of products through

 the whole process from the selection of raw materials to the storage of finished products. The perfect chemical 

composition matching, best microstructure by heating process, have reached the perfect combination of toughness 

and hardness.
