Salient Features: a) High hardness b) Good even wear resistance c) Low breakage d) High impact value e) No Mal-roundness
We would like to take this opportunity to introduce our products, with the hope that we may work with bright ideas in the future. As the raw material in producing steel balls is high quality alloy steel, we can assure the high hardness and good wear resistance of the products. Our company has obtained ISO9001 International Quality System Authentication. The quality of the products can meet the demand of client in different countries and areas. We would like to introduce our products as below for your reference.
