Steels - Determination and verification of the depth of carburized and hardened cases (ISO 2639:2002) EN ISO 2639:2002

Publication date:   Sep 12, 2003

Scope

ISO 2639 defines the case-hardened depth, and specifies methods for the determination of this depth, in steel.
It is applicable to
carburized cases and carbonitrided cases;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 met.
