(Flux Cored Stainless Wire)
▶︎ Characteristics:
LFC-811Ni1 is a titania type flux-cored wire.Use 100% CO₂ shield gas. It is designed for welding 590 N/mm² grade high tensile steel for low temperature.With good weldability ,stable arc, less spatter, good bead appearance and good impact toughness down to -30°C.
▶︎ Applications:
It is suitable for welding on construction machinery, shipbuilding, offshore, bridge, storage thanks and piping.
▶︎ Notes on Usage:
1. Use DC(+) polarity.
2 .Use 100% CO₂ shielding gas.
3. Pre-heat at 50-150℃ is required depending on steels, plate thickness and restraint.
4. Proper heat input can obtain required impact value.
