Elgaflux 500B

Flux for submerged arc welding

Classification

EN ISO 14174-A S A FB 1 55 AC H5

Description:

Elgaflux 500B is a high basicity agglomerated, fluoride-basic flux 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. Elgaflux 500B exhibits very good slag detachability,

even in narrow gaps, along with smooth bead finish and tie-in. The flux 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. Elgaflux 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 vessels, high strength line pipe, petrochemical, cryogenic and nuclear components.
