Steels. Determination and verification of the depth of carburized and hardened cases Ingestion-build-117251 Guidelines for the inspection1 Scope This International Standard defines the case hardened depth, and specifies methods for the determination of this depth, in steel. It is applicable to a) carburized cases and carbonitrided cases; b) parts that, when heat treated to final hardness, have a hardness of less than 450 HV 1 at a distance of three times the case hardened depth, from the surface. The case hardened depth is defined by special agreement where these conditions are not
