Category 
FCAW Flux-Cored
type 
High alloyed flux-cored wire for joining difficult to weld steel and buffer layers prior to hard facing.
applications 
• Repair jobs where high strength and toughness is required. • Joining austenitic manganese steels with themselves or with other steels. • Buffer layer before hardfacing and maintenance on air hardenable and « hard-to-weld steels ». • Armour plate and Joining 14% manganese steels.
Properties 

         • Special flux cored self shielded stainless steel wire for open arc welding
         • The weld beads produced have a self-releasing slag covering that leaves a clean surface
         • Sound deposits are obtained even in the presence of cross draughts
         • Primary choice for cladding and rebuilding application, suitable for joining and cladding
         • Provides maximum productivity for outdoor jobs
