Vanadium, Titanium and Tungsten Carbide – Polymet

POLYVAN O is an iron based metal cored wire, designed to produce weld deposits containing vanadium tungsten carbides. These carbides form during solidification of the weld puddle, and are evenly dispersed throughout a tough austenitic matrix. POLYVAN O’s wear resistance is higher than that of chromium carbide but less than tungsten carbide.
