Scope

Form: This specification covers a nickel alloy in the form of wire@ rod@ strip@ foil@ and powder and a viscous mixture (paste) of the powder in a suitable binder and procured in inch/pound units. MAM 4778 is the metric version of this AMS. Application: This filler metal has been used typically for joining corrosion and heat resistant steels and alloys requiring corrosion and oxidation resistant joints with good strength at elevated temperatures@ but usage is not limited to such applications. Also may be used as a corrosion and oxidation resistant hard coating. Safety - Hazardous Materials: While the materials@ methods@ applications@ and processes described or referenced in this specification may involve the use of hazardous materials@ this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
