Description
Features and Applications
ER-NiCrMo-4 is used for the welding of alloys that have similar chemical compositions, this includes dissimilar materials of nickel-base alloys, steels and stainless steels.
Due to the high molybdenum content, this alloy offers excellent resistance against stress & corrosion cracking, pitting and crevice corrosion.
Typically used on pipelines, pressure vessels, chemical processing plants, offshore oil platforms, gas facilities, power generation and marine environments etc.
