Metals have been the backbone of various industries for ages. The Aerospace, medical, and automotive industries are among those that rely heavily on metals. However, not all metals are created equal. AMS 5564 is a high-strength, low-alloy steel that has gained popularity because of its outstanding mechanical and physical properties. In this blog, we will dig deep into the composition of AMS 5564, its physical and mechanical properties, uses, hardness, and heat treatment.
What is AMS 5564?
AMS 5564 (also known as 304L Stainless Steel) is a material standard that specifies the requirements for high-quality stainless steel tubing used in aircraft hydraulic systems. This tubing is known for its durability, strength, and resistance to corrosion. Aerospace engineers rely on materials that meet high standards for quality, and the AMS 5564 sheet is no exception. It is tested and approved to ensure that it meets the stringent requirements for aircraft use. With its excellent performance and reliability, the AMS5564 is a trusted and important component in many aviation systems. Beyond aviation, this material is also used in other high-pressure applications where its strength and resistance to corrosion make it an ideal choice.
AMS 5564 Composition
AMS 5564 is classified as 304l Stainless Steel with a chemical composition that consists of Chromium (16-18%), Nickel (6.5-7.5%), Manganese (1%), Aluminum (0.75-1.5%), Carbon (0.09%), and Iron (Balance). This combination of elements gives it excellent corrosion resistance in various environments. Moreover, the alloy has a tensile strength of 1500 MPa and a yield strength of 1300 MPa. These characteristics make AMS5564 one of the strongest steel alloys.
