The welds offer excellent resistance to stress corrosion, cracking and pitting. The microstructure of the weld metal consists of austenite and ferrite. The ferrite content of the weld metal will be lower than the ferrite content of type 2205 base metal. Welding of duplex stainless steels calls for controlled welding parameters to achieve specified mechanical and corrosion resistant properties.<\/p>\n<p>&nbsp;<\/p>\n<h2>Features<\/h2>\n<p>Bare, corrosion-resistant, duplex welding rods for welding austenitic-ferritic stainless alloys of the 22% Cr, 5% Ni, 3% Mo types. 2209 has high general corrosion resistance. In media containing chloride and hydrogen sulphide, the alloy has high resistance to intergranular corrosion, pitting and specially to stress corrosion.
