Technical Information for A286 per AMS 5732
A286 per AMS 5732, is an iron-nickel-chromium alloy with additions of molybdenum and titanium. A286 is one of the most popular high temperature alloys. As one of the austenitic alloys it maintains good strength and oxidation resistance at temperatures up to 1300ºF. Due to it’s high strength and excellent fabrication characteristics A286 is used in various components of aircraft and industrial gas turbines. A286 is also widely used in the offshore oil and gas industry where the components are subject to high levels of heat and stress.
AMS 5732 possesses many favorable properties, including excellent strength at high temperatures, excellent corrosion resistance up to 1300 °F (700 °C), and low-temperature non-magnetic strength, down to -320 °F (-196 °C).
Because of that, it finds use in many fields, but mainly in the aircraft industry for jet engine components, industrial gas turbine parts, superchargers in internal-combustion engines, etc.
Additionally, AMS 5732 can be readily formed, and cold worked, just like other austenitic steels. Moreover, the parts can be machined using standard methods.
The alloy can be readily welded using traditional methods, including gas tungsten arc, gas metal arc, and shielded metal arc. Any nickel-based steel can be used as filler metal, but a filler wire of the same specification is recommended. Also, for optimal results, the weld bead should be raised, and the parts in the annealed condition.
