AA 312 FCAW Flux-Cored




AA 312

 
CATEGORY 
TYPE 
Rutile fluxcored welding wire developed for welding dissimilar steels with difficult weldabillity
APPLICATIONS 
Buffer layers before hardfacing, armor plate, exhaust systems, high, Manganese austenitic steel, heterogeneous welding, difficult to weld and unknown steels.
PROPERTIES 

Very good welding characteristics and not sensitive for cracks and fissures. High tensile strength with good corrosion and acid resistance. Scale resistance up to 1150ºC, crack and wear resistant, suitable for rebuilding wornout parts. Excellent corrosion resistance against high temperature liquid acids. Much better welding characteristics than solid wire.
