GB/T 224-2008
AbolishedDetermination of depth of decarburization of steels
钢的脱碳层深度测定法
Application Summary AI generated
This standard specifies the metallographic method for measuring the depth of decarburization in steels, which is the loss of carbon from the surface layer during heat treatment or hot working. It is applied in quality control and failure analysis for steel products such as bars, wires, and forgings, particularly in the automotive, aerospace, and tool manufacturing industries where surface hardness and fatigue resistance are critical. The standard ensures consistent evaluation of decarburization depth, guiding acceptance criteria for heat-treated components.
