Electrodes for Low Temperature Service

NITHERME-2.5L

AWS: SFA 5.5 E7018-C1L

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.

Precaution

1. Re-dry the electrodes at 250-300 C for one hour.

2. Restrict the heat input to a minimum during welding to achieve better properties.
