DESCRIPTION
Geeflux 550 is an agglomerated flux of fluoride basic type for joining and surfacing and applications with dissimilar steels. Mainly for high strength and cryogenic fine grained structural steels. The Si and Mn pick-ups and burn-off rates are Neutral because of its metallurgical behaviour. Flux is weldable with almost every wire electrode. The flux can be used for tandem and multi wire welding with DC and AC. Very good slag detach-ability.
