Type A-286 is an iron-based super alloy useful for applications requiring high strength and corrosion resistance up to 1300 degrees Fahrenheit and for lower stress applications at higher temperatures. A-286 can be hardened to a strength level. The alloy is also useful for low temperature applications requiring a ductile, non-magnetic high strength material at temperatures ranging from above room temperature down to at least -320 degrees Fahrenheit. This alloy can also be used for moderately corrosive applications in aqueous solutions. All of our A-286 is ordered to specific decimal thicknesses. See the list to the left for thickness ranges. A-286 alloy content is similar in chromium, nickel, and molybdenum to some of the austenitic stainless steels. Consequently, A-286 alloy possesses a level of aqueous corrosion resistance comparable to that of the austenitic stainless steels. In elevated temperature service, the level of corrosion resistance to atmospheres such as those encountered in jet engine applications is excellent to at least 1300°F (704°C). Used in many moderate temperature and stress applications in jet engines, such as low pressure turbines, compressors, shafts and afterburner parts.
Properties: Non-magnetic. A-286 is an austenitic alloy in the hardened and aged condition per AMS 5732, which has moderate strength and rupture characteristics up to 1300ºF (704°C). The alloy has good oxidation resistance for continuous service up to 1500°F (816°C) and intermittent service up to 1800°F (982°C). Can attain high strength levels when aged after cold work, and has wide application as high temperature fasteners and springs.
Hardness: The hardness of Aerodyne stock is typically 310 BHN and is supplied in the fully heat treated condition – 1800ºF (982°C) solution anneal plus 1325ºF (718°C) age for 16 hours. No further heat treatment is required.
Machinability: Rating: 25% of B-1112
Typical Stock Removal Rate: 40 surface feet/minute with high speed tools. 135 surface feet/minute with carbide.
Comments: More difficult to machine than AMS 5731 because it is aged hardened.
Density: 0.287 lbs/in3, 7.94 g/cm3
