Rutile type flux cored wire, designed for welding fine grained structural steels by using M21 shielding gas. Succesfully used in single and multi-pass welding in steel construction, offshore platform, shipbuilding and pipe laying. Provides weld metal with high toughness, down to -50°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 removing.
