durostat® - wear-resistant steels with best workability
durostat®
durostat®-steels are specially suitable for components exposed to high mechanical stress and heavy abrasion, e.g. loading devices, conveyors, excavator components, road machines, screens and crushers.
Additionally we deliver durostat B-steels as boron alloyed steels in as-rolled condition for components in agricultural machines (e.g. plows and harrows), shovels of wheel loaders, bodies of trough tipping wagons, cutting edges for front-end loaders or brick-molding boxes.
Advantages
- Longer service life: As a result of their high hardness durostat®-steels enable wear resistances many times higher than of conventional steels.
- Less weight: Due to the high hardness compared to conventional steels the thickness of durostat®-plates can be reduced significant. This results in lower dead weights and thus higher payloads.
- Best weldability: durostat®-plates can be welded without problems. Due to the relatively low carbon content preheating is not necessary for small thicknesses.
- Best Surface: durostat®-steels of small thickness 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 furnce scale from conventional hardening.
