PURPOSE: Welding material and method of producing welded joint are provided, which are used for welding of large-scale steel structures such as ships, bridges, tanks, construction machines and the like. CONSTITUTION: An iron based alloy which contains by mass%; 0.20% or less of C; 6.0 to 16.0% of Cr; 6.0 to 16.0% of Ni and whose martensitic transformation starting temperature (Ms point temperature) is in the range of 0-170 deg.C, inclusive of 0 deg.C and exclusive of 170 deg.C, is used as a welding material. With respect to a weld metal, the weld metal has a iron alloy composition which contains by mass%: 0.20% or less of C; 3.0 to 13.0% of Cr; 3.0 to 13.0% of Ni and whose martensitic transformation starting temperature (Ms point temperature) is in the range of 50-360 deg.C, inclusive of both 50 deg.C and 360 deg.C. |
