What is A286 alloy?
A286 alloy is an age-hardenable iron-based high-temperature alloy, classified as both a stainless steel and a specialty metal. It is known for its ability to maintain stable performance from extremely low temperatures (-320°F) to high temperatures (approximately 1300°F/700°C). Its main components include iron, nickel, chromium, molybdenum, and titanium, making it an ideal material for demanding applications such as aerospace (jet engines), gas turbines, and high-temperature fasteners.
What is the AMS equivalent of A286?
A286 alloy (UNS S66286) equivalent materials are specified by various standards like ASTM A638 Grade 660, ASTM A453 Grade 660, AISI 660, and DIN 1.4980, with specific forms covered by AMS 5525, AMS 5731, AMS 5732, etc., all indicating the same precipitation-hardenable iron-nickel-chromium superalloy used for high-strength, high-temperature applications in aerospace and turbines.

Applications
Super alloy A-286 is used in gas turbine forgings, fasteners, superchargers, cryogenic equipment, missile components, corrosive deep well hardware and jet engines.
Is A286 stainless steel magnetic?
A286 alloy is good for applications requiring high strength and corrosion resistance up to 1300°F (704°C). This alloy can be age hardened to a high strength level. The alloy is also used for low temperature applications requiring a ductile, non-magnetic, high strength material at range of temperatures.
Does A286 work harden?
Cold Working In the solution treated condition, Pyromet alloy A-286 can be satisfactorily cold drawn and formed. It is somewhat stiffer than stainless steels such as Types 316 and 310, and it work hardens rapidly. Machinability In general, the high temperature alloys are more difficult to machine than stainless steels.
What is the difference between A286 and 316?
A286 is a high-temperature alloy chosen for high strength at elevated temperatures and good corrosion resistance, while 316 is a standard stainless steel selected for its excellent corrosion resistance and general-purpose use. A286 is ideal for applications like jet engines, steam turbines, and aerospace components, whereas 316 is commonly used in chemical processing, marine environments, and food production.
What is the price of A286 material?
As of December 2025, the price of A286 alloy round bars ranges from $12.99 to $35 per kg; small orders of 10 - 99 kg are priced at $28 - $35 per kg, while bulk orders of 1000 kg and above can be as low as $12.99 - $15.99 per kg.
