Abranel 276 S
Nickel base electrode NiCrMo type
Description & applications
Basic coated electrode with an alloyed core wire for welding of Nickel-Base alloys (alloy C-276) and other highly corrosion resistant Ni Cr Mo-alloys as well as special stainless steel types. Stable arc, regular drop transfer, easy to watch weld pool, nice aspect of the weld beads. Very resistant in sulfurous acid environment, highly concentrated with chlorides and also in the presence of oxidizing solutions ( Fe Cl, Cu Cl ).
Main applications:
Welding of Off-shore components, boilers, containers, piping systems in the chemical and petrochemical industries as well as components of flue gas desulfurizing plants.

Welding Instructions
Redrying 2 h at 250-300°C. Joints to weld must be clean, exempt from grease, cracks. Guide electrodes with a slight declination, weld with a short arc and prevent a high heat input by applying the stringer bead technique (weaving max. 2 times core wire diameter).
