Elgaflux 251B
Classification
EN ISO 14174-A S A AB 1 87 AC H5
Flux for submerged arc welding
Description:
Elgaflux 251B is an agglomerated, aluminate-basic flux providing an optimum combination of excellent
operating characteristics and good fracture toughness properties down to –40oC.It is designed for butt
and fillet welding using single and multi-wire processes in mild, C-Mn and higher tensile steels. The
slag is self-detaching even in narrow joints, leaving a smooth, clean weld bead and the flux is highly
suitable for fillet welding using the twin-arc process. Elgaflux 251B can be used on AC and DC, with
up to 1000A on a single wire and is suitable for general fabrication, box girders, shipbuilding, pressure
vessels and line pipe manufacture.
