Moore, T J

The results of testing have confirmed the idea that cracking of weld metal in stainless steel is clearly an inverse function of ferrite content. For niobium-containing alloys the ferrite transforms to brittle sigma during exposure to elevated temperatures. Stress rupture data indicate that the electrode compositions H, C, and A appear suitable to join Type 347 stainless, since they are stronger than the base metal. Compositions 16-8-2, H, and C possess superior tensile ductility to the partially ferrite Type 347 weld metal (Composition A) in the 1500 to 2000 deg F range. Corrosion tests show that the Nb-bearing welds possess acceptably low corrosion rates in the as-welded and annealed conditions. The probable field of application for each electrode composition is outlined. (B.O.G.)
