I'm looking for a method for measuring case hardness depth. The Hardness layer is on the order of 1.5mm to 6mm. The method must be allow for portable inspections and be reasonably priced. Any assistance will be greatly appreciated.
Re: Case hardeness thickness Eddy current testing lends itself very well to testing for case hardening. You would need to have a standard and most of the instruments are meter type that are resonably Priced.
