ABSTRACT:
A nickel-chromium-titanium filler alloy for inert gas shielded-arc welding of 50% Cr, 50% Ni type alloys. The wrought alloy is characterized by a single phase austenitic microstructure and contains, by weight, from about 42 to about 46% chromium, from about 0.1 to about 1.8% titanium, from about 0.01 to about 0.1% carbon, and up to about 0.1% magnesium with the balance, apart from incidental elements, essentially nickel. The alloy provides sound welds having a two phase microstructure that afford elevated temperature strength and corrosion resistance equal to that afforded by base metals of the 50% Cr, 50% Ni type.
