40Cr shaft parts Seamless steel pipe for mechanical manufacturing Die steel
40Cr belongs to medium carbon quenched and tempered steel and cold heading die steel. The steel has moderate price and easy processing. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. Normalizing can promote the refinement of the structure, close to the equilibrium state, and improve the cutting performance of the blank. When tempered at 550 ~ 570 ℃, the steel has the best comprehensive mechanical properties. The hardenability of the steel is higher than that of 45 steel, which is suitable for surface hardening treatment such as high frequency quenching and flame quenching. 40Cr shaft part is one of the typical parts often encountered in machine. It is mainly used to support transmission parts, transfer torque and bear load.

40Cr and other alloy structural steels are suitable for shaft parts with medium precision and high speed. After quenching, tempering and quenching, these steels have better comprehensive mechanical properties. After quenching and tempering, this kind of steel is used to make mechanical parts which can bear medium load and medium speed, such as steering knuckle, rear half shaft of automobile, gear, shaft, worm, spline shaft and top sleeve of machine tool.
