Abstract
Weld deposit compositions with improved abrasion and corrosion resistance are provided by balancing percent weights of Chromium (Cr), Titanium (Ti), Niobium (Nb), and Boron (B) to allow the Chromium content of the weld matrix to be minimally reduced during carbide formation. The result is an enriched Chromium matrix that has excellent corrosion resistance in combination with highly abrasion resistant dispersed carbides.
