Abstract

The present invention relates to a duplex stainless steel alloy with austenite-ferrite structure, which in hot extruded and annealed finish shows high strength, good corrosion resistance, as well as good weldability which is characterized in that the alloy contains in weight-% max 0.05% C, 0-2.0% Si 0-3.0% Mn, 25-35% Cr, 4-10% Ni, 2-6% Mo, 0.3-0.6% N, as well as Fe and normally occurring impurities and additions, whereby the content of ferrite is 30-70%.
