ERNiCrMo-4

Description
ERNiCrMo-4 , This low carbon, nickel-chromium-molybdenum filler metal can also be used for dissimilar welding between nickel base alloys and stainless steels, as well as for surfacing and cladding.Due to high molybdenum content, this alloy offers excellent resistance to stress corrosion cracking and pitting and crevice corrosion. It can equivalent to: Oxford Alloy C-276 , FM C-276 ,Techalloy 276.

Applications
ERNiCrMo-4 offen used for groove welding of 9% nickel steels in the production of LGN storage tanks.
ERNiCrMo-4 also can be used for welding of materials of similar chemical composition, as well as dissimilar material of nickel base alloys, steels and stainless steels.
