The gear accuracy of the parking gear is 7, low carbon alloy steel, The material of Parking Gear is low-carbon alloy steel. Different carbon content of alloy steel can have different influences.

The yield point and tensile strength of steel will increase with the increase of carbon content. When the carbon content exceeds 0.23%, the welding performance of steel will deteriorate. Therefore, the carbon content of low alloy structural steel used for welding is generally not more than 0.20%. High carbon content will reduce the atmospheric corrosion resistance of steel, in the open yard of high carbon steel is easy to rust; In addition, carbon can increase the cold brittleness and age sensitivity of steel.

The main solid phase transformation of steel during heating is the transition from non-austenite to austenitic phase, that is, the process of austenitizing. It's all about the diffusion of carbon.
