OK Autrod 2509
A continous solid corrosion resisting "Super Duplex" wire for welding of austenitic-ferritic stainless alloys of 25% Cr, 7% Ni, 4% Mo, low C types. OK Autrod 2509 has high intergranular, pitting and stress corrosion resistance. The alloy is widely used in applications were corrosion resistance is of outmost importance. Pulp & paper industry, offshore and gas industry are areas of interest.
