Microindentation hardness testing is a very powerful tool for characterizing materials and diagnosing problems. It is a complicated process, however, and the subject is rarely taught in schools. 

We continue our discussion on how to interpret carburized case depths by focusing on measurement techniques. These methods are also applicable to cases produced by nitriding, nitrocarburizing, boronizing, and induction or flame hardening. Let’s learn more.

The Internet is a wonderful place, full of invaluable information available, literally, at our fingertips. Did you ever wonder, however, how much of the information you’re viewing is truly accurate? 

If the steel part has been surface treated by carburizing, carbonitriding, austenitic nitrocarburizing, ferritic nitrocarburizing, nitriding or boronizing, one cannot always grind into the finished surface.

The result of hardness testing is what will determine the success of the heat-treatment procedure and the material’s response to that heat treatment.
