The brief introduction of steel shaft

  Steel shaft's main material is carbon steel and alloy steel. Carbon steel is cheaper than alloy steel, less sensitivity to stress concentration, so it is widely used.

  Common carbon steel has 30-50 steel, the most commonly used is 45 steel. To ensure that the mechanical properties, it should do quenched and tempered or normalizing treatment. Steel shaft that is not important or smaller force and drive shaft can use Q235-Q275.

  Alloy steel has high mechanical strength, hardenability is also good, and it can transfer large power, reduce the quality and improve the wear resistance of the shaft neck. Alloy steel has 12CrNi2 12CrNi3 20Cr 40Cr 38SiMnMo. The steel shaft material can also be made of alloy cast iron or nodular cast iron. Shaft blank is formed by casting, so it is easy to get a reasonable shape.

  These materials vibration absorbing performance is good, which can use heat treatment method to obtain the desired wear resistance, stress concentration sensitivity is low. Because the casting quality control is not easy, the reliability is not as good as steel shaft.


Steel shaft,axle shaft and motor shaft which are producted by the professional manufacturer and exporter Fenghua Zhaoxu Micro Shaft Co., Ltd. are sold at home and overseas.
