Ultra Wear is a high chromium carbide overlay deposited on a high grade mild steel plate. This forms an extremely hard surface that provides exceptional wearability and slideability. The process is achieved by applying accurately blended metal powders to a mild steel base plate by melting both with a system called sub-arc welding.

Fusion takes place under a thick flux cover, thereby eliminating oxide formation and gas and pick-up, resulting in inclusion free deposit. It also produces a relatively even and smooth surface by welding passes approximately 1½" in width covering the material.

With all Chromium Carbide Weld deposits, it is common for fine cracks to form across all weld seams. These cracks do not propagate into the base material and will not affect the wearability of the overlay.

Ultra Wear can easily cut to custom sizes by using Plasma arc. Plates can be welded together using common electrodes to join backing plates which does not affect the wear resisting properties. Ultra Wear can be rolled or vent to custom shapes.

Metallurgical properties achieved in this accurately controlled process utilizing the proper blend of metal powders results in an overlay with an evenly distributed chromium carbide and extreme hardness. By using small carbides, Ultra Wear obtains a consistent wear on the matrix that hold them in place. Various grades are made with differing proportions of high carbides in a tough matrix to suit individual applications.

Since Chromium Carbide has a very low coefficient of friction, combined with the smooth finish of Ultra Wear, it is suitable for areas where customers have problems with hold back of their product.

Ultra Wear has excellent forming qualities even with thinner thicknesses both chrome in or out of formed radii. This is the result of a consistent dilution zone.

Plasma Cutting


SHAPING CUTTING & FORMING

Ultra Wear can be easily cut to dimensions using Plasma Arc or Arc Air gouging. Ultra Wear can be rolled both with and across the weld seams. Whenever possible, chromium carbide overlay should be formed to the inside of the radius, however, it can be formed to the outside of bends.

When forming chrome carbide with the weld seam or to the outside of bends, a greater radius is required.

 

 

WELDING OF ULTRA WEAR

When structural strength of the weld is required, the following procedure applies:

Mild Steel Base Material E7018
Fusion Point of Mild Steel & Chrome E309L
Hard Surface Stoody 33 or 35


When structural strength of the weld is "not" required, the following procedure applies:

Mild Steel Base Material #7018
Hard Surface Stoody 33 or 35
Wear resisting properties are not affected by welding

 

 

MACHINING

Ultra Wear cannot be machined or drilled by conventional means. Both countersunk and square holes must be cut by Plasma Torch.


INSTALLATION

Weld beads on overlaid plates should be installed at 90 degrees to the flow of material whenever possible, in order to obtain maximum wear life.

In some cases, to prevent turbulence, it is necessary that weld beads run in the direction of flow (Fan Blades).
