The product has special wear resistance and is widely used in metallurgy, Mining, building materials, chemical and other industries. It has been proven by wide using experience with such feature of 2.1times higher service cycle than that made from common carbon steel ball, breaking rate less than 2%
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.
