Exaton NiCrMo-4
NiCrMo-4 is a low carbon nickel-chrome-molybdenum alloy of type alloy C-276. It is a versatile alloy with excellent wet corrosion resistance in oxidizing and especially in reducing media. However, in oxidizing chloride containing environments alloy UNS N06022 (2.4602) is preferred where NiCrMo-10 is a better matching welding consumable. Applications for NiCrMo-4 are found in aggressively corrosive media such as chemical processing plants, pollution control, pulp and paper production, waste treatment and for the recovery of sour natural gas. NiCrMo-4 is used for joining alloy UNS N10276 (2.4819) and other nickel-chrome-molybdenum alloys. It can also be used for dissimilar metal joining of nickel alloys, stainless steels and low-alloy steels. NiCrMo-4 can be used for surfacing low alloyed steels. Applications for NiCrMo-4 are found in cryogenics, components in pulp and paper plants such as bleaching vessels, flue gas scrubber systems, components in sour-gas service, sulphuric acid coolers, chlorine gas, hypochlorite and chlorine dioxide atmosphere. NiCrMo-4 is also used in combustion-resistant components for high pressure oxygen service. It is used for MIG/MAG welding.
