20130294820 | WELDING COMPOSITIONS FOR IMPROVED MECHANICAL PROPERTIES IN THE WELDING OF CAST IRON - 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. | 11-07-2013 |
20130260177 | ABRASION AND CORROSION RESISTANT ALLOY AND HARDFACING/CLADDING APPLICATIONS - 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. | 10-03-2013 |
20120097658 | CHROMIUM FREE HARDFACING WELDING CONSUMABLE - Compositions for Chromium-free hardfacing welding consumables are provided that include between approximately 0.3% and approximately 1.5% Carbon, between approximately 0.2% and approximately 2.5% Manganese, between approximately 0.3% and approximately 1.3% Silicon, between approximately 1.3% and approximately 5.5% Boron, between approximately 1.0% and approximately 4.0% Nickel, between approximately 1.0% and approximately 6.0% of at least one of Titanium and Niobium, and between approximately 0.1% and approximately 2.0% Tungsten and/or Molybdenum. Additional welding consumable compositions and weld deposit compositions are also provided to provide hardfacing materials with little or no Chromium content. | 04-26-2012 |
