This is a continuation of part 3, which can be found here.

If the steel part has been surface treated by the following, one cannot always grind into the finished surface to prepare for hardness testing.

Having the right tools in our toolbox or knowing who to call and rely on makes any job go easier, faster and better.

If the steel is decarburized, it means the surface of the steel has lost carbon. If either of the conditions described in part 1 exists, the steel will have been subjected to...

The result of hardness testing is what is used as the first level of interpreting the correctness of the heat-treatment procedure.

The DiaMet hardness testing software upgrade is now available for legacy Wilson testers. DiaMet can integrate and transform legacy testers to improve quality management using the software’s database.

The microstructure of a material represents its fundamental properties, and most heat treatments are performed to tailor these properties to a specific need. Good metallographic preparation allows faster and more-accurate quality control – whether a microstructural inspection or performing specific tests such as case-depth analysis.
