Patent ID: 8124007

Claim:
A stainless steel weld overlay having a matrix with a bulk composition comprising, by percent mass: between approximately 0.5% and approximately 1.5% Carbon; between approximately 0.1% and approximately 2.0% Manganese; between approximately 0.1% and approximately 0.9% Silicon; between approximately 14.0% and approximately 18.0% Chromium; between approximately 6.0% and approximately 10.0% Nickel; between approximately 1.5% and approximately 3.5% Molybdenum; the elements of both Titanium and Niobium in an amount between approximately 0.5% and approximately 8.0%; and greater than 0% and less than approximately 0.15% Nitrogen; wherein both second phase Titanium Carbide and second phase Niobium Carbide precipitates are incorporated in the stainless steel weld overlay; wherein the composition is adjusted such that the Carbon content in the matrix is at or below approximately 10% of the bulk Carbon content, the balance being tied up as the carbides of Titanium and Niobium.
