ENICrFe-2 (Alloy A)


Alloy Type:

ENiCrFe-2  Alloy A electrodes are used for the welding of nickel-chromium-iron alloys to themselves as well as for dissimilar welding between various nickel alloys and carbon or stainless steels.  There is a large range of applications from cryogenic temperatures up to 1500⁰F.  These electrodes can also be used for overlay cladding where similar alloy is needed.
