Stainless electrode high corrosion resistant
Rutile-basic coated electrode for welding fully austenitic highly corrosion resistant stainless steels (Sanicro 28, Uranus B28 ) of the same composition or lower alloyed. 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.
(Sanicro is a trade name of Sandvik, Uranus is a trade name of Creusot Loire Industries)

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.
