Electrodes for Low Temperature Service
NITHERME-2.5L
AWS: SFA 5.5 E7018-C1L
EN ISO CODE:
A low hydrogen electrode yielding low carbon, 2.5% Ni in the weld deposit. It is ideally suited for welding fine-grained steels and Ni steels especially for service temperatures down to minus 73°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.
