One Surface hardened steel parts: through what kind of science fiction film deal with a hard wear-resistant surface layer, a moderate heart. If the gear transmission torque, and must have enough strength, and the process of the impact of the impact load and the system toughness, gear meshing process in a strong wear, and wear resistant gear must be high overall strength, therefore, "table hard" performance.
Two Structural steel: many important parts, such as shaft, screw, and other important links, in the bearing of the great stress and impact load, and other complex stress, the requirements of high strength and toughness of the composite mechanical properties. In order to achieve the above requirements, the steel parts must be quenched and high temperature tempering treatment (i.e., quenching and tempering treatment) quenching, high temperature tempering after the organization of the. The amount of carbon in the quenched and tempered steel is that the low carbon content is not easy to quenching and tempering, and the need of high strength; low carbon content is the brittle fracture in the use of human nature.
