Main Feature

Outstanding Features:

1、That such feature of Stable metallographic structure,  high hardenability and the difference between the internal and external hardness values is not greater than HRC3, Keeps the whole ball and road being smooth, round and undeformable as well as  without peeling during the working process;

2、Good surface shape, dense structure , and there are no defects such as air holes and shrinkage.
