Patent ID: 8735776

Claim:
A weld deposit composition produced from a flux-cored or metal cored welding wire comprising, by percent mass: between approximately 0.7% and approximately 2.0% Carbon; between approximately 0.2% and approximately 0.5% Manganese; between approximately 0.5% and approximately 1.1% Silicon; between approximately 2.0% and approximately 8.0% Chromium; between approximately 2.0% and approximately 6.0% Molybdenum; between approximately 2.0% and approximately 5.0% Tungsten; between approximately 2.0% and approximately 8.0% a sum of Niobium and Titanium; between approximately 1.0% and approximately 2.5% Vanadium; between approximately 0.2% and approximately 0.9% Boron; and a balance of Iron, wherein amounts of Titanium and Niobium are balanced with amounts of Carbon and Boron to form intermetallic carbides and borides that act as grain refiners, the ratio of Titanium or Niobium to Boron being about 4.4 for Titanium Boride, about 2.2 for Titanium Diboride, about 8.6 for Niobium Boride, and about 4.3 for Niobium Diboride.
