Basicity：2.3
Suitable for welding carbon steel and 490N/mm2 grade steel in ship-building, pressure vessel and offshore structure.

KF-880+KW-1 is suitable for welding 490N/mm² grade steel.
KF-880 is an agglomerated fluoride-basic type flux, providing excellent low-temperature impact toughness, good bead appearance, and excellent slag detachability.
When used with EH-14 welding wire, excellent low-temperature impact toughness at -40 °C can be obtained.
Ideal for welding applications such as pressure vessels, shipbuilding, and offshore structures.
