For those considering this material in their next project, it’s essential to understand its properties, uses, and treatments. In this blog post, we’ll provide some valuable insights into the aspects of AMS 5380 that you need to be aware of.
AMS 5380 Composition
AMS 5380 is an iron-based alloy with chromium, nickel, and copper primary components. The alloying elements give it excellent strength, corrosion resistance, and toughness while maintaining its durability. Another significant feature of this alloy is its low carbon content, which reduces the chances of corrosion cracking in welded joints.
AMS 5380 Physical Properties
AMS 5380 has a 7.87 g/cm³ density and a melting point of approximately 1398°C. The alloy exhibits high resistance to both oxidation and reduction while retaining its exceptional strength at elevated temperatures. Moreover, it possesses excellent thermal and electrical conductivity, making it suitable for various applications.
AMS 5380 Mechanical Properties
One of the primary characteristics of AMS 5380 is its exceptional mechanical properties. Even at high temperatures, the alloy shows excellent tensile strength, yield strength, and elongation properties, making it an ideal material for critical applications. It is also known for its toughness, fatigue, and wear resistance.
AMS 5380 Uses
AMS 5380 is mainly used in the aerospace industry for its high strength, toughness, and corrosion resistance. Its high-temperature performance and thermal stability make it ideal for use in jet engine components, landing gear, and control surfaces. The alloy is also used for manufacturing precision parts in the medical industry, such as orthopaedic implants and surgical tools.
AMS 5380 Hardness
AMS 5380 can be hardened through precipitation hardening, which results in increased strength and hardness. After heat treatment, the alloy can attain a Rockwell hardness of up to 52 HRC, depending on the desired level of hardness required.
AMS 5380 Heat Treatment
Heat treatment of AMS 5380 involves a solution annealing treatment at around 1040°C for at least ½ hours, followed by cooling in water or air. This is followed by a precipitation hardening treatment at about 550°C for 4-8 hours, followed by air cooling.
Conclusion
AMS 5380 offers a unique combination of strength, durability, toughness, and corrosion resistance, making it an ideal material for aerospace and medical applications. While the alloy’s properties are exceptional, it’s important to note that proper heat treatment, welding, and post-weld heat treatment are required to achieve the desired results. Ultimately, if you’re looking for a high-performance alloy that delivers exceptional results in harsh environments, AMS 5380 is worth considering for your next project.
