COROFLUX HL
CLASSIFICATION
DIN EN 760 | SA CS 2 Cr 64 DC
GENERAL CHARACTERISTICS
COROFLUX HL is an agglomerated flux for submerged arc 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. The flux is nearly burn-off neutral for C and Mn, and slightly alloying in Si and Cr. This flux can also be used for dual-wire feeding and for strip welding.
WELDING RECOMMENDATIONS
