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.
