Mining pick is a part of coal mining and coal mining machinery and equipment, is a small tool for dropping coal and crushing coal. From the point of view of the specific application of the quarry, the cutter body material is mostly 42CrMo, 35CrMnSi and other alloy structural steel, and it is also the newly developed Si-Mn-Mo quasi-bainite steel used in the quarry. Coal industry standard: the strength of the cutter body is 40 ~ 45HRC, and the fracture toughness is not less than 49J/cm2. In the process of processing, the raw material of the cutter body shall exceed or exceed the physical property index value specified by the tempering treatment.
