SUPRATHERME(SPL)H4R

AWS: SFA 5.1 E7018-1H4R IS: 814 EB5626H3JX EN ISO CODE: 2560-A E 42 4 B 3 2 H5

Supratherme(Spl)H4R is a 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. Some typical applications include maintenance welding of all types of C-Mn steels, heavy tensile steels, heavy structures, plants & equipments subjected to static or dynamic loading. Typical Applications Include: • Coaches • Wagons • Penstocks • Boilers & Pressure vessels • Earth moving machines etc.

Precaution

1. Restrict the heat input, use short arc and stringer bead.

2. Re-dry the electrodes at 250 C for 1 hour, if expose to atmosphere.
