Rutile type flux cored wire, designed for welding fine grained structural steels by using M21 mix shielding gas. Succesfully used in single and multi-run welding in steel construction, bridge, offshore platform, shipbuilding and pipe laying. Owing to it's easily controllable weld pool and fast freezing slag, suited for welding in all position easily. It's metal recovery provides ability of good gap bridging and filling property. Because of nickel alloy, weld metal yield and tensile strength is high and weld metal is proper to use on fine grained steels at operating temperatures 450°C down to -40°C. Diffusible hydrogen content is 5 ml per 100 g deposited weld metal, so highly resistant to cold cracking. Has a stable and quite arc with low spatter loss. Has easily removable slag and generally self removed.
