Hammer forging:
The raw material is forged to a certain deformation by the air hammer, when the compression ratio increased, the micro-structure become more compact so that the hardness and the toughness can be improved.
Heating:
we use the electric furnace instead of the traditional coal stove, the biggest advantage is that all the steel bars can accept the most approriate temperature during the heating progress. It affect the hardness and toughness directly.
Steel Cutting:
the steel bars should be cut into small pieces according to the size of steel balls required by the order.
Specification:
1) No deformation
2) High hardness Good wear resistant
3) Size:Dia20mm-150mm
4) Breakage<1%
5) Certification: ISO9001,SGS.
