VAUTID W3
For thin-walled components (30mm maximum) subject to low impact and high abrasion
VAUTIDÂ W3 is first in the range of highly wear-resistant casting materials developed by VAUTID engineers. This alloy has been specifically designed for thin-walled components which are subject to severe abrasion.
VAUTID W3 is a ânaturally hardâ material, i.e. it is already hard in its as-cast condition, and no heat treatment is needed to activate its wear-resistant properties. Which means that components cast in genuine VAUTIDÂ W3 offer a clear cost advantage.
Because of this materialâs high wear-resistance, components made from VAUTIDÂ W3 cannot be machined.
Recommended applications:
- Cast components that are exposed to temperatures up to 400°C.
- Thin-walled components (<Â 30Â mm) that are subject to severe abrasion, e.g. tiles used as liners in mixing plants or agitators.
Mechanical properties
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.
