Application Summary AI generated

This standard specifies the method for determining and verifying the depth of carburized or carbonitrided case layers in sintered ferrous materials. It is applied in the metallurgy and powder metallurgy industries for quality control of components like gears, bearings, and structural parts that undergo surface hardening treatments. The standard ensures consistent measurement techniques for evaluating case depth in porous sintered materials, which differ from wrought steels.
