A filler material for welding is characterized by the following chemical composition (amounts in % by weight): 0.05-0.15 C, 8-11 Cr, 2.8-6 Ni, 0.5-1.9 Mo, 0.5-1.5 Mn, 0.15-0.5 Si, 0.2-0.4 V, 0-0.04 B, 1-3 Re, 0.001-0.07 Ta, 0.01-0.06 N, 0-60 ppm Pd, max. 0.25 P, max. 0.02 S, remainder Fe and manufacturing-related unavoidable impurities. The material has outstanding properties, in particular a good creep rupture strength/creep resistance, a good oxidation resistance and a very high toughness. |
