The structure of HG785D steel plate after conventional heat treatment is tempered sorbite. For parts that require wear resistance on the surface (such as gears and spindles), induction heating surface quenching and low temperature tempering are performed, and the surface structure is tempered martensite. The surface hardness can reach 55HRC ~ 58HRC. After quenching and tempering, the yield strength of the alloy quenched and tempered steel is about 800MPa, and the impact toughness can reach 22HRC ~ 25HRC at 800kJ / m2. If the cross-sectional size is large and not hardened, the performance is significantly reduced.
