Composite wearplates

for reliable, all-purpose wear protection _Other generic names:_ _/High Chromium Carbide Overlay composite wear plate, CCO overlay plate_ _/Hardfaced plates, high carbide wear resistant steel_ _/bimetal wear resistant chromium carbide wear plate_ _/abrasion resistant wear plate, abrasion resistant steel_ Hardcarb composite wear plates consist of a steel backing plate on which a very hard wear-resistant alloy is deposited using a proprietary _Carb-o-inject_ welding process. This alloy may contain hardphases of extreme hardnesses depending on the application conditions and expected service life (hardlayer contains stress-relieving hairline cracks). Common hardphases include: - **Chromium carbides –** reliable, cost-effective - **Complex carbides –** carbides of niobium, vanadium, titanium etc. - **Borides –** for effective erosion resistance - **Metallic Borocarbides –** near-nanostructured hardphases - **Tungsten carbides –** angular, spherical in iron or nickel matrix Hard coatings from 1.0 mm upto 15.0 mm are easily achievable, though most common are the 3mm to 8 mm thickness range. Backing plate can be any weldable steel suited for the application.

Hardcarb composite wear plates should not be compared with sheets coated using conventional [hardfacing](https://en.wikipedia.org/wiki/Hardfacing) techniques such as [flux-cored wire welding](https://en.wikipedia.org/wiki/Flux-cored_arc_welding), [submerged arc welding](https://en.wikipedia.org/wiki/Submerged_arc_welding) etc. Our wear plates are manufactured using proprietary carb-o-inject process which is still today, one of the only rare techniques of obtaining very hard, dense, closely packed primary carbides from top to bottom of the hardfacing deposit. It is this unique property that ensures the superior performance of Hardcarb wear plates as compared to all competitors worldwide. Supply alternatives include: - **Overlay bead profile –** Our sophisticated CNC machines allow linear, zig-zag, curved, circular and various other weld bead profiles. - **Wide range of hardfacing alloys –** more than 25 grades to suit every wear need in thicknesses ranging from 1mm to 35mm. - **Backing plate options –** carbon steels, fine-grained steels, stainless steels etc. Any weldable steel in any thickness can be provided.

Typical applications include protection of large surface areas which are under high mechanical load and require great operational reliability. Examples include: - **Vibratory and rotary screens, feeders** - **Rotors for centrifugal fans** - **Linings for hopper, casing, mixers, separators etc.** - **Linings for cement, slag, raw, coal mill components**
