At current, our product use 40CR steel material, dia 4 to 14 use YG8 cemented carbide, dia16 to 38 use YG9C cemented carbide. And use gas welding and high frequency welding, then we use salt bath quenching. HRC 47 more or less3.
Our new product will use 42CrMo steel material. All of the product use automatic welding, and use a continuous furnace with gas quench for brazing and hardening in protective atmosphere. It will be reduce the HRC index, but will get a more high intention for a better use. We also change the carbide quality, in quality it will close Ther Luxemburg carbide standard.
