The tooth body is made of high quality cold extrusion 42CrMo, high density not decarburization. Numerical control lathe processing ensures consistent size. With special heat treatment process of 40-45 degrees, its surface is almost no oxidation, tooth head using isothermal quenching process, its hardness doesn't reduce. Production of cemented carbide by formal domestic companies, stable quality can accord customer needs to add welding wear-resisting layer, hardness reaches more than 65 degrees.
