For components over 40 mm thick that are subject to impact and abrasion
With a very high proportion of chrome carbides embedded in an extremely stable matrix, VAUTID W78A produces castings which achieve a long service life, even under extreme conditions. VAUTID W78A has proved ideal in situations where severe impact is combined with highly abrasive media.
- Cast components that are exposed to temperatures up to 400°C.
- Components that are subjected to very severe abrasion and significant impact g. hammers, impact heads, chisels, and beater bars.
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.
