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.

Abstract: Weld deposit compositions with improved crack resistance, improved wear resistance, and improved hardness are provided by controlling matrix grain size and balancing Titanium and/or Niobium with Carbon and/or Boron content. Additionally, the presence of coarse chromium carbides is drastically decreased to reduce the amount of check-cracking. Preferably, the weld deposit is produced from a flux-cored or metal-cored wire. The weld deposit characteristics include a matrix having a fine grain size, small evenly dispersed carbides within the matrix, and a small amount of Carbon in the matrix.

Abstract: Compositions for stainless steel weld overlays having enhanced wear resistance are provided by incorporating second phase Titanium Carbide (TiC) and/or Niobium Carbide (NbC) into matrices of various types of stainless steel such as 316L and 420. Preferably, TiC and NbC precipitates are formed in-situ during the weld overlay process while minimizing the amount of Carbon (C) going into solid solution in the matrix of the weld overlay.

Abstract: A weld deposit produced from a coated welding electrode for use in welding cast irons is provided by the present invention. Preferably, in one form of the present invention, the weld deposit composition comprises between approximately 54% and approximately 60% Nickel, between approximately 3.5% and approximately 5.5% Manganese, and between approximately 0.9% and approximately 1.4% Carbon. The weld deposit is preferably formed by using a coated welding electrode having a coating composition between approximately 0.3% and approximately 4.0% Magnesium and rare earth metals and oxides. The resulting weld deposit exhibits improved ductility, fracture toughness, and resistance to cracking.
