Abstract
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.
