What is AMS 5557 Tubing?
AMS 5557 is a specification of a seamless tube made from Stainless Steel 321 (SS 321), austenitic stainless steel that has extraordinary resistance to high temperatures. SS 321 has the addition of titanium to prevent it from becoming sensitized and to give it better high-temperature strength, hence making it suitable where another stainless steel grade would not perform due to chromium carbide formation.
This tubing mostly finds application in aerospace, automobiles, chemical processing industries, and pressure vessels where there is a need for corrosion and high-temperature strength. AMS 5557 tubing has very good oxidation and scaling resistance in temperatures up to 900°C (1650°F) with fairly good weldability and fabricability. Its mechanical properties are resistant to high and low temperatures and other unfavorable conditions required for long service.
It is generally cold drawn and thus has finished and close fits, which are necessary for use in fluid power, fuel, hydraulics, and pneumatic operations. 321 stainless steel aerospace tubing is a material specification for military purposes defined by MIL-T-8606 and is used in aerospace applications such as aircraft, aircraft engines, and missiles, where the tubing is subjected to very harsh conditions. The tubing has both high strength and flexibility; it also has low fatigue characteristics, thus suitable for high pressure, high stress applications.
