Depth beneath the surface of an object to which (surface) hardening penetrates.
Note :
Material with 50% martensite is sometimes considered as an indication of hardening. Where necessary, case depth can be specified as flame-hardened depth, induction-hardened depth, nitriding depth, case-hardened depth etc. In practice, the case depth in a surface-hardened object is usually measured by determining the distance from the surface at which the hardness reaches a pre-determined value.
