ERNiCrMo-3

Description
ERNiCrMo-3 contains low iron (Fe less than 1%) and is used for welding of nickel-chromium-molybdenum alloys, also for cladding and welding dissimilar based metals such as Ni-Cr-Mo alloys to stainless and carbon steels, The Ni-Cr-Mo alloy system provides excellent resistance to oxidizing and reducing enviroments. The high molybdenum content provides good stress. Pitting and crevice corrosion resistance.. It can equivalent to: Oxford Alloy 625 FM625 Techalloy 625.

Applications
ERNiCrMo-3 can be used for welding of dissimilar joints between nickel-chrome-molybdenum alloys and stainless or carbon or low alloy steels. Also be used for cladding as well as for spraying applications. ERNiCrMo-3 with low iron (less than 0.8%) is preferred in various applications where dilution of iron must be controlled to the minimum. The high alloy content of ERNiCrMo-3 enables it to withstand highly corrosive environments. Due to its molybdenum content, this alloy offers resistance to stress corrosion cracking, pitting, and crevice corrosion.
