Machining Stability Of X210crw12 Steel Key Factors Affecting - China

To enhance the machining stability of X210CrW12 steel, attention must be paid to the following key factors: 3.1 Inherent Material Properties

The high hardness and high carbide content of X210CrW12 steel result in poor machinability.

High temperatures and vibrations tend to occur during cutting, leading to reduced surface quality and shortened tool life, which in turn compromises machining stability.

3.2 Dimensional Changes and Deformation During Heat Treatment

During the quenching process, X210CrW12 steel is prone to developing internal stresses due to phase transformations and uneven cooling, resulting in workpiece deformation or cracking.

Oil quenching, in particular, involves rapid cooling rates that make the material more susceptible to dimensional changes and deformation.

3.3 Residual Stresses

Residual stresses are generated in the steel during manufacturing (such as rolling or forging) and rough machining.

The release of these stresses during subsequent finishing or heat treatment can cause workpiece deformation, severely affecting machining accuracy and stability.
