Forging Wear-resisting Steel Ball

Forging Wear-resisting Steel Ball are made of wear-resistant raw materials, such as 60Mn, 65Mn, through forging, stamping, heat treatment and other processes, eliminates the defects on the surface and inside of the steel ball, such as shrinkage cavity, crack, transgranular and so on, and then obtains the dense internal structure of the product, reduces the phenomenon of grain coarseness, so that the product has good impact resistance, wear resistance and good toughness, not easy to break, which is favored by the majority of users
