The chemical composition (%) of the material for shaft retaining ring is 0.62 - 0.70 for carbon, 0.17 - 0.37 for silicon, 0.90 - 1.20 for phosphorus, 0.035 for phosphorus, 0.035 for sulfur, 0.25 for nickel, 0.25 for chromium and 0.25 for copper
Shaft with the material properties of the ring: it is widely used carbon spring steel, compared with 65 steel, with high strength, hardness, elasticity and hardenability, the critical quenching diameter in water is generally 30 ~ 50mm , The oil is generally 16-32mm, heat treatment, thermal sensitivity and temper brittleness tendencies, water quenching easy to crack, the general use of oil quenching, cross-section size> 80 should be water quenching oil: after annealing is still good machinability, but Cold deformation and low plasticity, poor welding performance.
