Applications and Features

(1)    Suitable for welding 550N/mm² grade steel.

(2)    Compared with flux cored wire, KMX-80Ni1 has higher deposition rate, faster travel speed, superior arc wetting and better bead appearance.

(3)    Excellent toughness at -45℃ due to 1% Ni content.

(4)    Ideal for welding LPG tank, such as A226, A235 and A236.
