1,Forging steel ball surface quality is good, good impact resistance, strong toughness, good wear resistance, invulnerability to breakage and loss of circle.Forging and stamping method, we use is the metal heating until the temperature reaches 1050 DHS C (plus or minus 50 C) DHS, pressure of forging machinery for metal blank, make its produce plastic deformation in order to obtain certain mechanical properties, a certain shape and size of forging processing method
2.By forging can eliminate the metal smelting process of as-cast loose defects, such as optimizing the microstructure, at the same time because of the intact metal flow, forging generally better than that of the same material on the mechanical properties of the castings.Forging steel ball to wear must choose the wear-resisting material, or some company independent research and development of high wear-resistant alloy steel materials.
