This standard specifies the meaning and determination of steel-parts carburizing and carbonitriding hardened-case depth. This standard is applicable to carburizing and carbonitriding hardened layer; and the parts that, when they are final-heat-treated, have a hardness of less than 450 HV at a distance of three times the case-hardened depth, from the surface. For steel-parts that can not meet the above conditions, it shall be determined in accordance with a special agreement. For steel-parts of which, at a distance of three times the hardened-case depth from the surface, the hardness is greater than 450 HV, this standard is still valid, provided that a limiting hardness value that is greater than 550 HV (in steps of 25HV) is selected for the case-hardened depth.
