Quality factor is significant to Dongfang.For years,according to quality and environment management system,

specified programs and quality brochures,Dongfang cultivates a quality & inspection team to manage the whole

  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.
