The merger of the Thyssen and Krupp steel operations at September 1, 1997 was clearly displayed on the head office of the new company.
The spin-off of the steel business is triggered by negotiations on a merger with Krupp Stahl AG, which fails to come about in 1983. In the following years Thyssen adapts its steel production to the market and streamlines its structures. Thus, on October 1, 1992 Thyssen Edelstahlwerke AG is merged into Thyssen Stahl AG.
The discussions resumed in the 1990s concerning a joint venture with Krupp result in collaborations in tinplate (Rasselstein Hoesch GmbH), electrical steel (EBG Elektroblech Bochum GmbH) and stainless flat products (Krupp Thyssen Nirosta GmbH) in 1995. In 1997 - after Fried. Krupp AG Hoesch-Krupp withdraws its intention to acquire a majority stake in Thyssen AG - the flat steel activities of Thyssen Stahl AG and Krupp Hoesch Stahl AG are combined in Thyssen Krupp Stahl AG.
