Hardening Shop

Here you will find the website of Deutsche Edelstahlwerke Härterei Technik GmbH: www.dew-haerterei.de/en/

For some years now, Deutsche Edelstahlwerke Härterei Technik GmbH has been part of Deutsche Edelstahlwerke - a company of Swiss Steel Holding AG.

Swiss Steel Holding AG employs around 10,000 people and is one of the world's leading manufacturers, processors and distributors of long products. This means that the entire production chain, from steel production and processing to final heat treatment, can be offered from a single source - and in the world's most important markets.

What does this mean for our hardening customers?

Processes can be fully reproduced and traced. The usual high quality standard can thereby be extended even further. Processes are continuously optimized through the constant exchange of information and know-how within the production chain. This leads to shorter production and delivery times.
