Stainless Steel Electrodes
ES 2209 A5.4: E 2209-17 / EN 1600: E 22 9 3 N L R 32
Description
ES 2209 Is Rutile coated electrode designed for ferritic - austenitic duplex steels . filed of applications are in off- shore engineering and in the chemical industry .besides offering high mechanical strength and toughness , the weld metal is also noted for excellent resistance to stress corrosion cracking and pitting resistance. ES 2209 offers excellent positional weldability , and thus is prefectly suited for pipe welding besides the good wetting characterisitics , slag removability resistance To prosity and reliable toughness down to - 20 ?C
