1: 20Cr4 steel introduction
20Cr4 is an alloy carburized steel according to EN ISO 683-17-2014, corresponding to the Chinese brand 20Cr. After heat treatment, 20Cr4 has moderate strength and toughness without tempering brittleness tendency. After chemical heat treatment, the surface has high hardness and wear resistance, and has corrosion resistance. Cold deformation plasticity is high, can be cold drawing. High temperature normalizing or tempering, good machinability, weldability is also good.

Application | 20Cr4 is mainly used to manufacture parts with high core strength requirements, working surfaces to withstand wear, and small sections, or carburized or carbonitriding parts with complex shapes and small loads, such as machine tool change gear, gear shaft, CAM, worm, piston pin, claw clutch and so on. It can also be used in the tempered state to manufacture parts with high working speeds and moderate impact loads. |
For cold drawn bar, usually the delivery condition is cold drawn, annealed/QT, peeled/black surface
