Abstract
Abstract An iron-nickel-chromium alloy with which crack-free sound welds are produced for fuel elements and tube-to-tube sheet assemblies having low carbon (0.05 max) and up to 0.40 each of titanium and aluminum, the Ti being eight to 10 times the carbon and the aluminum four to six times the carbon. The Ti and/or Al suppress the formation of massive Cr23C6 molecules. Also a method of welding iron-nickel-chromium alloy in which Ti and/or Al are present to prevent cracks from forming.
