For components over 40 mm thick that are subject to impact and abrasion
This alloy is designed to provide maximum through-hardening on wall thicknesses above 40 mm. VAUTID W72 offers outstanding resistance against wear from abrasion and moderate impact. The wear-resistant properties of this material can be suspended by heat treatment. This is especially advantageous in the case of components that require machining.
- Cast components that are exposed to temperatures up to 400°C.
- Cast components that require machining.
- Components with wall thicknesses greater than 40 mm which are subject to abrasion and impact, e.g. hammers, plungers, agitators.
VAUTID use white cast iron materials produced to DIN EN 12513 grades GJN-HV520 – 5.5602 and GJN-HV600(XCr18) – 5.5609 for components exposed to abrasion or to a combination of abrasion and impact. Materials developed in-house by VAUTID are used in impact mills, crushers and conveyor units, commonly installed in recycling plants, asphalt works or power generation plants. Typical components include lining elements, mixer tools, pump parts, hammers and beater bars. VAUTID materials VAUTID W7, VAUTID W72 and VAUTID W72H can all be machined.
