OK Autrod 2209 is a duplex stainless steel for welding type 2205 duplex stainless.
As a SAW wire it can be used in combination with OK Flux 10.93.
A continuous, solid, corrosion-resistant, duplex wire for the GMA welding of austenitic-ferritic stainless alloys of the 22% Cr, 5% Ni, 3% Mo types. OK Autrod 2209 (''Duplex'') has high general corrosion resistance. In media containing chloride and hydrogen sulphide, the alloy has high resistance to intergranular, pitting and especially stress corrosion. The alloy is used in a variety of applications across all industrial segments. OK Autrod 2209 is usually welded with Ar/(1-3%) O2 as the shielding gas.
Former name of this product was OK Autrod 16.86
