Description
Rutile-basic coated electrode for Superduplex ferritic-austenitic stainless steels
Offshore applications exploit the high resistance to pitting (typical pitting resistance equivalent number “PREn” of 43) and stress corrosion cracking in seawater. It is also highly resistant to caustic alkalis and phosphoric acid. Widely used in oil and gas production and process. Its rutile-basic coating ensures an excellent combination of welding performance in all positions, except for vertical down, and a high resistance to cracking providing smooth arc transfer.
