ERNiCrMo-3 (Alloy 625)
Alloy Type: A5.14, NICKEL AND NICKEL ALLOY Bare Electrodes and Welding Rods
ERNiCrMo-3 Nickel Alloy 625 is used for MIG, TIG and SAW welding of nickel-chrome-molybdenum alloys. This very versatile filler metal can be used for welding of dissimilar joints between nickel-chrome-molybdenum alloys and stainless carbon or low alloy steels. It can also be used for cladding as well as for spraying applications. Nickel Alloy 625 with low iron is preferred in applications where dilution of iron must be controlled to a minimum.
