Electrodes for Low Temperature Service
SUPRATHERME(SPL)MOD-H4R
AWS: SFA 5.1 E7018-1H4R
EN ISO CODE:
Moisture resistant
hydrogen controlled basic coated electrode for producing tough and ductile weld
of radiographic quality in Boilers, Pressure vessels, Medium carbon steels,
Cast steel and problematic steels. The weld metal is clean and has low level of
impurities, thus having unique properties. The electrode can be used in all
conventional positions of welding. It is ideally suited for welding carbon
steels used in the construction of equipment subjected to heavy dynamic load,
impact and severe service conditions in sour gas service.
