COROFLUX 200

CLASSIFICATION

DIN EN 760 | SA FB 1 65 DC
BFB 4 543 DC 12 M 2-16

GENERAL CHARACTERISTICS

COROFLUX 200 is a highly basic agglomerated flux for hardfacing. This welding flux is recommended for the welding of mill rolls and continuous casting rolls in conjunction with martensitic CORODUR flux cored wires. However it can be used for other CORODUR submerged-arc wires with the approval of our technicians. The slag that is formed, is very easily removable and the thickness of the weld bead can be up to 5mm. This flux can also be used for dual-wire feeding and for strip welding.

APPLICATION

Non-alloying powder, especially for welding of rolls.
