Deutsche Edelstahlwerke in Stuttgart, Germany is a member of the Schmolz + Bickenbach AG group of companies which, with 150 years of experience, 11,000 employees and sales exceeding €4 billion, is the world’s largest producer, processor and distributor of special steel long products. The company offers customers a ‘one-stop-shop’ for heat treatment processes including plasma nitriding. Leading major German automotive sports car manufacturers rank amongst their list of clients, and Zwick has equipped the laboratory with all of its hardness testers – the most recent being the premier ZHU250 TOP Universal Hardness Tester. This machine has expanded the capability of the laboratory to carry out Rockwell, Vickers, and Brinell tests, and includes an innovative revolver system incorporating four indenters.

Similar systems require three or more objective lenses to cover the application range but, due to Zwick’s unique digital zoom technology, the ZHU250 requires only two. This enables a fast throughput of tests, and many different types of test can be carried out on the same machine with very high accuracy and repeatability. The test results are also sent to the host computer system via a computer interface.
