PROBLEM TO BE SOLVED : To provide a welded joint and a welding material having excellent corrosion resistance in an environment where metal dusting is easy to be generated such as a heat exchange type hydrocarbon reforming device and a waste heat recovering device, and further having excellent high temperature strength and weldability. SOLUTION : In the welded joint having excellent metal dusting resistance, a base material and a weld zone both have a composition comprising, by mass, 0.01 to 0.45% C, 0.01 to 2% Si, 0.01 to 2% Mn, ≤0.03% P, ≤0.01% S, 15 to 35% Cr, 40 to 78% Ni, >2 to COPYRIGHT : (C)2006, JPO&NCIPI
