Electrodes for Low Temperature Service
NITHERME-3.5(SPL)
AWS: SFA 5.5 E8018-C2
EN ISO CODE:
Nitherme-3.5(Spl) is a low hydrogen iron powder electrode depositing 3.5%Ni weld metal. It is pleasing operating characteristics and weld metal is of radiographic quality. Weld metal possesses excellent toughness at sub-zero temperatures. Ideal for welding fine grained Nickel steels for service temperatures down to minus 73 C.
Typical applications include pressure vessels, piping, valves and tanks used for storage, transportation and distribution of liquefied gases.
