Overlaid welded sheets are universally applicable. They are made with special welding processes. They consist of a weldable base material and an adapted hard cover. Usually standard steel, special steels are also used for special applications.
The wear layer consists of a CCr-Fe system with primary chromium carbides to achieve high hardness.
Hard coated slabs can be cut into drawing-oriented components using the latest cutting technologies, plasma, laser or waterjet cutting. Subsequently, cold or hot deformation is possible to produce self-supporting parts of the installation (pipelines, cyclones, classifiers, etc.).
