FCW Sub 307
Description & applications
• Metal cored stainless steel wire for gas shielded arc welding
• 18% chromium - 8% nickel - 6% manganese deposit
• Enhanced productivity, improved weldability, better wetting properties compared to solid wires
• Excellent weld metal quality and X-ray soundness
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.
