摘要：
In the present invention, 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°C, inclusive of 0°C and exclusive of 170°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°C, inclusive of both 50°C and 360°C.
