Electrodes for Low Temperature Service
SUPRATHERME-Ni (SPL) MOD
AWS: SFA 5.5 E8018-G
EN ISO CODE:
It is basic coated, low hydrogen, iron powder type electrode yielding a 1.0% Ni in the weld metal. Radiographic quality welds having excellent cracking resistance. Weld metal of excellent toughness to withstand heavy dynamic loading and impact. Ideally suited for welding fine grained steels, low alloy steels subjected to sub-zero temperature applications down to minus 60°C. Ideal for welding, heavy sections, highly restrained joints subjected to dynamic loading. Ideal for pressure vessels, tanks, spheres, etc.
