Brief analysis: chemical composition of shaft retaining ring

Chemical composition of shaft retaining ring material (%): carbon: 0.62 - 0.70, silicon: 0.17 - 0.37, manganese: 0.90 - 1.20, phosphorus ≤ 0.035, sulfur ≤ 0.035, nickel ≤ 0.25, chromium ≤ 0.25, copper ≤ 0.25
Material characteristics of shaft retaining ring: It is a carbon spring steel with a wide range of uses. Compared with 65 steel, it has higher strength, hardness, elasticity and hardenability. The critical hardening diameter is generally 30~50mm, generally 16-32mm in oil, there is a tendency of overheating sensitivity and tempering brittleness during heat treatment, easy to crack during water quenching, oil quenching is generally used, section size> 80 should be water quenched and oil cooled: machinability after annealing It is still good, but the cold deformation plasticity is low and the welding performance is poor.
