Description:
Elgaux 400B is a high basicity agglomerated, uoride-basic ux designed for welding Cr-Mo creep
resistant steels. The very low impurity levels in the ux 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.
Elgaux 400B can be used on both AC and DC, but AC is recommended for optimum impact proper-
ties. Elgaux 400B exhibits very good operability characteristics, including good slag detachability in
narrow gap joints. Typical fabrication sectors are pressure vessels, power generation and petrochemi-
cal industries.
