Most sugar chains are with case hardened bushes and rollers.
20Cr/20CrMnTi/20CrMo/20CrNiMo components are heat treated by multi-purpose furnace. By adjusting the temperature, gas pressure and other parameters, the multi-purpose furnace can control the depth and hardness of the carburized layer, meet the requirements of different components, and improve the hardness, surface strength and wear resistance of the components.
