FW 2594

AWS: SFA 5.9 ER2594 EN ISO CODE: 14343-A W 25 9 4 NL

FW 2594 is a solid wire for TIG welding, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. The weld metal exhibits high strength, high impact energy, and resistance to stress corrosion cracking, pitting, and crevice corrosion. The weld metal possesses excellent corrosion resistance in marine & paper environments. Examples of application areas are: Oil and gas industry, Off shore plat forms, Petrochemical plants, Mechanical and structuralcomponents. It is suitable for welding.
