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
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.
