LKT-NiCr-3
AWS A5.14 ERNiCr-3
Characteristics and Applications: LKT-NiCr-3 is use for welding base metal such as UNS number N06600. This includes ASTM grades B163, B166, B167 and B168. It is suitable for dissimilar welding using various nickel alloys to stainless steels or carbon steels, as well as for overlaying carbon steels. It is also used for welding 9% nickel steels to one another having high impact strength at low temperatures. The weld metal has high strength and good corrosion resistance, with oxidation resistance and creep-rupture strength at elevated temperatures.
