| Application and Properties: |
|
Agglomerated semi-basic
flux for welding low alloy steels (Ys<450 Mpa), pipe
steels according to DIN 17172 and API 5L steels up to
X70. High speed welding with single and multi-wire (up
to 3 wires). High speed on spiral welds in production of
pipes. Good wetting properties, flat welds and nice bead
profile, without reinforcement and undercut. Low
hydrogen levels (max. 5ml/100g)and very good low
temperatures toughness properties. Due to it's hardness
is >240HV, is resistant to sour gas environment,
fulfils NACE TM-0284 (solution A). Excellent slag
release, high wear resistance of individual flux grains.
