The influence of raw materials on the quality of shaft processed products

No matter what is made, the selection of raw materials is very important. This is also true when we are processing shafts. Shaft parts manufacturers will determine the corresponding process of raw materials according to specific use occasions, so that they can meet the requirements.



　　 In order for shaft parts to have corresponding strength, toughness and wear resistance, different materials need to be selected and supplemented by different heat treatment processes to meet people's needs.

　　 To give a few common examples, 45# steel is a common material for shaft parts. It is cheap and after quenching and tempering (or normalizing), it can get better cutting performance, and it can obtain higher strength and Comprehensive mechanical properties such as toughness, the surface hardness after quenching can reach 45～52HRC; 40Cr and other alloy structural steels are suitable for shaft parts with medium precision and high speed. After quenching and quenching, this kind of steel has better comprehensive mechanical properties. Performance; bearing steel GCr15 and spring steel 65Mn, after quenching and tempering and surface high-frequency quenching, the surface hardness can reach 50～58HRC, and it has high fatigue resistance and good wear resistance, which can produce higher precision Shaft parts.

　　Raw materials have a great influence on the quality of shaft processed products. We need to find certain rules so that when producing corresponding shaft products, we can select suitable materials for processing and make the quality of the products better.
