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 o 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.
