2 High hardness. Ultra-high wear resistance. Wear-resistant steels with excellent processing properties. durostat grades are wear-resistant steels with excellent processing properties from voestalpine Grobblech. durostat -steels are specially suitable for components exposed to high mechanical stress and heavy abrasion, e.g. loading devices, shovels of wheel loaders, bodies of trough tipping wagons, conveyors, excavator components, road machines, screens and crushers.

3 The advantages Longer life As a result of their high hardness, durostat steels have a wear resistance many times higher than that of conventional steels. Less weight Due to the high hardness compared to conventional steels, the thickness of durostat plates can be reduced significantly. This leads to lower dead-weights and thus higher payloads. Best weldability durostat 400 can be welded without problems. Due to the relatively low carbon content preheating is not necessary for small thicknesses. Best surface durostat 400 up to 50 mm and durostat 450 up to 30 mm are produced online by accelerated cooling directly after hot rolling. Thus a thin homogeneous secondary scale is built, which is easy to remove compared to furnace scale from conventional hardening.

4 Production process durostat steels are melted according to the LD process (oxygen top blowing process). The high hardness is achieved by accelerated cooling after hot rolling or by conventional hardening. Chemical composition durostat grades are characterized by modern, low carbon alloy concepts. Low carbon equivalent values indicate excellent welding properties. Heat analysis (guaranteed values) Steel grade mass in % C Si Mn P S Al tot.
