AMS 5542 INCONEL ALLOY – Composition, Properties, and Uses

Composition of AMS 5542 Inconel Alloy

AMS 5542 Inconel alloy is primarily composed of nickel, chromium, and iron. Nickel, being the primary constituent, accounts for a significant portion of the alloy’s weight, typically ranging between 50% and 60%. Chromium is added to enhance corrosion resistance, particularly against oxidizing environments. Iron, while present in a smaller quantity, contributes to the alloy’s mechanical strength.

In addition to these primary elements, AMS 5542 Inconel alloy contains smaller amounts of other metals such as molybdenum, titanium, aluminum, and carbon. Molybdenum improves the alloy’s resistance to corrosion and creep, while titanium and aluminum contribute to the formation of protective oxide layers. Carbon, in its trace amounts, helps refine the grain structure and enhance the alloy’s mechanical properties.
