Carburizing/Nitriding/Hardening Layer Depth Measurement

Purposes:

To check the component's the penetration depth and organizational changes after surface hardening or carburizing, nitriding treatment.

Applications:

Surface treatment on steel by carburizing, nitriding, decarbonization, carbonitriding, induction hardening steel.
