CORROSION RESISTANT ALLOY

The invention relates to metallurgy and more particularly to nickel-based alloys intended for use in aggressive oxidising environments. The present nickel-based corrosion-resistant alloy contains: = 0.006 wt.% carbon, = 0.1 wt.% silicon, = 1.0 wt.% manganese, 22.8-24.0 wt.% chromium, = 0.75 wt.% iron, 12.0-14.0 wt.% molybdenum, 0.01-0.03 wt.% niobium, 0.01-0.06 wt.% titanium, 0.1-0.2 wt.% aluminium, 0.005-0.01 wt.% magnesium, = 0.015 wt.% phosphorus and < 0.012 wt.% sulphur, with the remainder being nickel and unavoidable impurities. L'invention concerne la métallurgie et notamment les alliages à base de nickel destinés à l'exploitation dans des milieux oxydants agressifs. L'alliage résistant à la corrosion à base de nickel comprend, en % en masse: carbone =0,006, silicium =0,1, manganèse =1,0, chrome 22,8-24,0, fer =0,75, molybdène 12,0-14,0, niobium 0,01-0,03, titane 0,01-0,06, aluminium 0,1-0,2, magnésium 0,005-0,01, phosphore =0,015, soufre
