Product Application

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.
