Mining is one of the most important fields of application today when the focus is on dealing with abrasive and aggressive media. Since mines are reaching greater depths today than ever before, environment protection legislation is demanding more sustainable extraction methods. Against this background, operational reliability of the components plays an important role. Replacing grey cast iron with bronze where the medium is acidic and the application of new materials such as chromium and duplex steels ensure dependability of the components in use. The materials have to achieve a high degree of toughness while, at the same time, providing good resistance to stress corrosion cracking.

Standard and high-performance stainless steels are used as a result in many areas of mining: in screens and pumps, fluidised bed boilers, heat exchangers, pipes and tanks, containers, cathode sheets and textured components.
