Standard: 

EN ISO 14172-E Ni 6625

AWS A5.11 ENiCrMo-3

GB/T 13814 ENi6625

Description: AK-ENiCrMo-3 nominal compositionis 60%Ni-22%Cr-9%Mo-Fe-3.5%Nb+Ta, is Ni-Cr-Mo type of manual electrode; Due to the high alloy content, can be used in a widerange of temperature , from low temperature to 540℃; Has high strength level and corrosion resistance under room and high temperature, which includes pitting resistance, crack corrosion resistance, and stress release corrosion resistance in sulfuricacid environment; Stable arc, beautiful weld bead appearance, few spatter, easy slagremoval, excellent blowhole resistance.and stable deposited metal mechanical properties.

Application: Suitable for welding Ni-Cr-Mo series alloy.such asInconel 601/625,ASTM B443.Alloy 20, incoloy800,800H,825.can also be used for welding 9%Ni steel;Low hydrogen type manual electrode, can be used for cladding on steel surface.and dissimilar steel welding between steel and nickel alloy.
