Nital Etch Inspection

Nital Etch Inspection

Nital Etch, also referred to as temper etch, is a check to see if there is material damage or grinding damage on a part. The areas which have been overheated or exposed to higher temperatures while machining can have residual tensile stresses and lower hardness. Nital Etch inspection works by exposing the material or part in question to a mixture of alcohol and nitric acid. Damaged areas will be darker than their surrounding areas.
