|G20CrNiMo Bearing Steel Bars |
G20CrNiMo special steel also has excellent toughness in the core which can bear high impact load and good comprehensive performance and resists certain temperature because of Mo element.
G20CrNiMo Bearing Steel Bars description
G20CrNiMo material is under Chinese standard GB/T 3203. It is a common alloy carburizing bearing steel with super hardness and abrasive resistance and contact fatigue resistance on the surface of the bearing. G20CrNiMo special steel also has excellent toughness in the core which can bear high impact load and good comprehensive performance and resists certain temperature because of Mo element. Therefore, it is usually for turbine gear rotor, valve section forgings of Connecting Rod of Internal Combustion Engines and so on.
