Elgaflux 400B
Classification
EN ISO 14174-A S A FB 1 55 AC H5
Flux for submerged arc welding
Description:
Elgaflux 400B is a high basicity agglomerated, fluoride-basic flux designed for welding Cr-Mo creep
resistant steels. The very low impurity levels in the flux produce an extremely clean weld metal,
particularly with respect to P pick-up, and enable high impact strength properties to be achieved, even
after step cooling heat treatment.
Elgaflux 400B can be used on both AC and DC, but AC is recommended for optimum impact properties. Elgaflux 400B exhibits very good operability characteristics, including good slag detachability in
narrow gap joints. Typical fabrication sectors are pressure vessels, power generation and petrochemical industries.
