FLUX CORED WIRE OF BASIC TYPE
IDENTIFICATION
GFC 550
CLASSIFICATION
EN 758: T 42 4 M M 2 H5, DIN 8559: SG B1 CY 4254
DESCRIPTION
Fluxcored wire has operating characteristics typical for basic type consumables. The weld metal exhibits excellent mechanical and is therefore outstanding for welding steels having a higher carbon content, easy slag removal, porosity free welds.
