OK Autrod 2509
A continuous, solid, corrosion-resistant, “Super Duplex’’ wire for welding austenitic-ferritic, stainless alloys of the 25% Cr, 7% Ni, 4% Mo, low C types. OK Autrod 2509 has high intergranular-corrosion, pitting and stress-corrosion resistance. The alloy is widely used in applications in which corrosion resistance is of the utmost importance. The pulp and paper industry, offshore and gas industry are areas of interest.
