EXTREME ABRASION RESISTANCE OPTIMIZED FOR FINE PARTICLES

CHROMEWELD™ Nb PLUS Niobium Carbide Overlay Plate Engineered for Fine Particle & Extreme Abrasion

CHROMEWELD™ Nb PLUS weld deposit consists of primary chromium carbides combined with niobium carbides in an austenitic matrix.

By comparison, CHROMEWELD Nb PLUS contains a more abrasion resistant deposit to traditional chrome carbide plates. Depending on the specific environment, wear life can be extended 30-60%. This plate also offers better wear resistant at elevated temperatures due to its enhanced chemistry.

Performance In High Temperatures

By comparison, CHROMEWELD™ Nb PLUS contains a more abrasion resistant deposit to traditional chrome carbide plates. Depending on the specific environment, wear life can be extended 30-60%. This plate also offers better wear resistant at elevated temperatures due to its enhanced chemistry. Standard Plate size is 90” x 120”. CHROMEWELD™ Nb PLUS displays excellent abrasion fine particle resistance and will withstand continuous moderate impact. Standard thickness range from 1/8” on ¼” (.375”) through ½” on ½” (1”)

CHROMEWELD™ Nb PLUS Fabrication Facts

Cutting: Plasma burning, air arc, abrasive saw cutting, or waterjet.

Machining: The overlay surface can be finished by grinding only. EDM, plasma arc cutting, or carbon-arc gouging may produce countersunk holes for bolts. Pre-machined mild steel inserts may be welded into straight holes for additional machining. CHROMEWELD Nb PLUS cannot be machined by ordinary methods.

Cold Bending: Material is not readily formable due to its extreme surface hardness.

Welding: CHROMEWELD Nb Plus 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™ Nb.

Mechanical Information

CHROMEWELD Nb PLUS typical hardness ranges from 63-68 HRC based on weld deposit thickness. The surface of plate is a composite of chromium, niobium, and vanadium carbides in a chromium austenitic matrix. The surface of the plate exhibits numerous hairline cracks which are a natural stress relieving phenomenon that is essential to the performance of the plate and enable it to be formed, bent, and rolled without damage.
