Description:
Elgaux 500B is a high basicity agglomerated, uoride-basic ux designed for use where optimal low
temperature impact energy and CTOD fracture toughness properties are required. It produces low
oxygen (O) weld metal , approximately 300ppm, resulting in excellent impact toughness down to -60°C
and below, together with very low hydrogen levels. Elgaux 500B exhibits very good slag detachability,
even in narrow gaps, along with smooth bead nish and tie-in. The ux is non-alloying with respect to
Si and Mn and mechanical properties can be controlled by choice of suitably alloyed Elgasaw wires.
It is suitable for multi-pass butt welding of medium and high tensile steels and also low alloyed steels
using single and multiple wire systems. Elgaux 500B can be used on AC and DC, with up to 1000A
on a single wire and is highly suitable for stringent fabrication sectors such as offshore, pressure ves-
sels, high strength line pipe, petrochemical, cryogenic and nuclear components.
