Tungsten carbide Overlay For STRENUOUS ABRASION
CHROMEWELD™ W Tungsten Carbide Fine Particle Extreme Abrasion Overlay Plate
CHROMEWELD™ W is a material designed to withstand your most severe abrasion applications. This overlay plate combines the benefits of our premium CHROMEWELD™ chemistry along with the addition of tungsten carbide deposited throughout the matrix. Our manufacturing process produces a plate that has tungsten carbide dispersed throughout the entire matrix.
Extreme Abrasion With Tungsten Carbide
The typical hardness range of CHROMEWELD W is from 70-75 HRC depending upon the deposit thickness. Wear deposit consist of chrome & tungsten suspended in a cast iron like tungsten alloyed matrix.
The surface of the plate is a composite of tungsten carbide combined with chromium iron carbides. The plate’s surface displays numerous hairline cracks which are crucial to the performance of the plate. This plate can be formed, bent and rolled without damage.
CHROMEWELD™ W Fabrication Facts
Mechanical Information
CHROMEWELD™ W typical hardness range from 70-75 HRC depending upon deposit thickness. The surface of the plate is a composite of tungsten carbide combined with chromium iron carbides.
Welding: CHROMEWELD™ W overlay plate can be joined by welding the substrate to work piece using JADCO FUSION™ Universal, a high strength, work hardened stainless steel that can be welded to dissimilar metals, designed for harsh working environments. Please note that 309 weld wire/rod and similar wire/rod may also be used. Typical structural rods/wires such as E7018, E71T1 and similar may also be used so long as the weld bead stays 2mm below the hard face material. For substrate to substrate joining use Jadco Fusion Universal or 309 weld wire/rod. Liner plates can be plug welded to the work piece. Stud welds can be applied. It is highly recommended that stainless steel studs be used. All weld seams, plug weld holes, bolt holes and all joints exposed to wear should be protected with surface welds of JADCO FUSION™ W.
