Electrodes for Low Temperature Service
NITHERME-2.5
AWS: SFA 5.5 E8016-C1
EN ISO CODE:
A low hydrogen DC(+) electrode yielding 2.5% Ni in the weld deposit, ideally suited for welding fine-grained steels and Ni steels especially for service temperatures down to minus 60 C. The weld metal possesses strength combined with excellent sub-zero temperature notch toughness. Typical applications include storage tanks, pressure vessels, containers and piping for liquefied gases like propane and butane.
