Abracrom 904
Stainless electrode highly corrosion resistant
Description & applications
Rutile-basic coated electrode for welding fully austenitic highly corrosion resistant stainless steels as 904L, B6. Good weldability in all positions, except vertical down, stable arc, good slag removal, regular finely rippled weld beads. Due to its alloy composition, high Mo-content and Cu, the weld metal is suited against attacks by phosphoric- and sulfuric acids, it shows a high resistance against pitting and stress corrosion in chloride containing media. It is used at operation temperatures up to 400°C.
Main applications:
Pulp and paper industry, transport containers, installations of the chemical industry.

Welding Instructions
Redrying 2-3h at 250-300°C. 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). Interpass temperature: < 150°C.
