Measurement of Carburized Layer Depth of 18Cr2Ni4WA Steel after Carburizing
The method of determining the carburized layer depth of 18Cr2Ni4WA steel after carburizing is studied.The clear boundary between the carburized layer and the core is easily obtained by metallographic method after isothermal quenching at 280℃.The carburized layer depth of 18Cr2Ni4WA steel can also be measured by metallography method after quenching and tempering,but it is difficult to identify the transition zone.The process of using Vickers hardness method to determine the carburized layer depth of the steel is complicated and affected by the material and heat treatment process,but it can reflect the performance of the steel after the final heat treatment.
