Applications and Features

(1)      Suitable for welding 490N/mm² grade steel.

(2)     KF-880 is fluoride-basic agglomerated flux providing low hydrogen weld metal, good bead appearance and slag removal.

(3)      The combination of KF-880 and KW-12KH provides the excellent toughness at -60℃.

(4)      Ideal for welding shipbuilding, offshore structure and foundation of offshore wind mill.
