A unique low hydrogen type electrode yielding 3.5% Ni in the weld deposits. Specially designed for welding fine-grained steels and nickel steels for service temperatures down to minus 80°C. Typical applications include pressure vessels, piping systems, valves and tanks used for liquefied propane, butane, ethane, acetylene, CO2 and even liquefied ethylene.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300°C for 2 hours.
2. Restrict the heat input to a minimum during welding to achieve better properties.
