PURPOSE:To improve the high-temp. creep rupture strength of a weld metal by incorporating specific ratios of C, Si, Mn, Cr, Ni, Mo, W, V, Nb, and N into a wire and adding Mo and W in a specific range thereto. CONSTITUTION:This wire contains, by weight, 0.03-0.15% C, <= 0.25% Si, 0.4-2.5% Mn, 8.0-13.0% Cr, 0.05-1.3% Ni, 0.5-2.85 Mo, 0.2-2.5% W, 0.03-0.30% V, 0.02-0.12% Nb, and 0.010-0.100% N, and further, the W and Mo in the range enclosed by points A, B, C are incorporated therein. The high- temp. creep strength of the weld metal is improved by the wire constituted in the above-mentioned manner. |
