PURPOSE:To obtain deposited metal having excellent low temp. toughness by specifying the components in a welding flux and deposited metal. CONSTITUTION:The components of a flux contain, by weight %, 40-60% CaF2, 20-30%Al2O3, 5-15% CaO or MgO, and 5-15% SiO2 and further contain <=5% MnO and <=10% Cr2O3. By using such flux and an austenitic stainless steel electrode, the deposited metal which contains <=0.08% C, 0.2-0.7% Si, 0.5-6% Mn, <=0.03% P, <=0.006% S, >=17% Cr, <=3% Mo, <=0.035% oxygen, and <=0.1% nitrogen and of which the content of delta ferrite calculated by the equation Iis negative is obtained. |
