Characteristic
100Cr6 bearing steel has good comprehensive properties, quenching and tempering, high hardness and uniform, good wear resistance, high contact fatigue strength. The hot workability of steel is good, and it has good machinability.
100Cr6 bearing steel, toughness is good, with good tempering stability, heat treatment deformation is small. The steel carbide distribution, not to the precipitation of carbide network and easy to be normalized to eliminate, by normalizing can remove the mesh and plate coarse carbides. However, the compressive strength and wear resistance, poor processing. The steel surface residual carbon content of 0.6%, 0.7% of the decarburized layer, due to the carbide due to the decrease of surface layer of overheating sensitivity increases. The surface hardness can reach 60 to 62HRC after the normal heating and quenching, but the bending strength is decreased by 40% - 50%. The grain size of the surface layer reaches 7, and the heart is 10.
The good performance of steel forging, due to decarburization, need to be heated in a neutral atmosphere or protective atmosphere furnace. Impose forging heat quenching and tempering treatment can obtain fine tempered sorbite martensite structure, simplify the process, saving the electricity, both good cutting performance, and ideal heat treatment microstructure.
The steel heat softening temperature of 320 DEG C, the hardenability of steel ratio, oil quenching hardening depth of 40 - 50mm. The steel zero time holding quenching toughening technique, can eliminate rub silk = plate for conventional quenching heating oxidation and decarbonization cause early failure, inhomogeneous austenite or martensite refinement can, rub fire after cryptocrystalline martensite or fine acicular martensite body, the strong organization good toughness.
