FCW TS 307
Special flux cored self shielded stainless steel wire for open arc welding
Description & applications
- Special flux cored self shielded stainless steel wire for open arc welding
- 18% chromium - 8% nickel - 6% manganese deposit
- 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
- Suited for joining
- Provides maximum productivity for outdoor jobs
APPLICATIONS
- Repair jobs where high strength and toughness combined with workhardening are required.
- Joining austenitic manganese steels with them or with other steels.
- Buffer layer before hardfacing.
- Maintenance on air hardenable and « hard-to-weld steels ».
- Armour plate.
- Joining 14% manganese steels.
