STAINLESS STEEL WELD OVERLAYS WITH ENHANCED WEAR RESISTANCE

摘要

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.
