GEEFLUX 303

CLASSIFICATION
AWS/SFA 5.9 : ER 308L; AWS/SFA 5.9 : ER 316L;
AWS/SFA 5.9 : ER 309L; AWS/SFA 5.9 : ER 309LMo;

DESCRIPTION
Specially designed for welding Austenitic and Austenitic-Ferritic stainless steels. This basic, but neutral flux will produce outstanding results in the welding of the standard Austenitic and heat-resisting stainless steels, when using the corresponding wire electrodes according to EN ISO 14343 or ASME II C: SFA-5.9. Due to the basic flux characteristics of Geeflux 303 most grades of the 300-stainless steels can be welded using single or multiple wire submerged-arc processes. It is also suited for joint-and overlay welding of nickel alloys, together with adequate Ni-base wire electrodes.
Geeflux 303 produces smooth flat weld beads when fillet welding. If appropriate welding parameters are applied a finely ribbed surface along with self-releasing slag is yielded as well as weld beads that are free of slag inclusions. The metallurgical behaviour of the flux is neutral (C-neutral, low Si pick-up and  low Mn burn-out) without Cr- or other alloy compensation.
