SAE AMS 5709J:2019 PDF Download

SAE AMS 5709J:2019 is a standard that specifies the requirements for a nickel alloy that is highly resistant to both corrosion and heat. This alloy consists of 58% nickel, 19.5% chromium, 13.5% cobalt, 4.3% molybdenum, 3.0% titanium, 1.4% aluminum, 0.05% zirconium, and 0.006% boron. The material can be produced using either consumable electrode or vacuum induction melting at a temperature of 1975 °F (1079 °C).

The nickel alloy bars and forgings produced under this standard are subjected to a series of heat treatment processes to ensure their stability and precipitation hardening. These processes involve solutionizing the material at high temperatures, followed by stabilization and precipitation heat treatment. The resulting bars and forgings exhibit excellent resistance to both corrosion and high temperatures.

This standard provides the necessary guidelines for manufacturing a high-quality nickel alloy material that can be used in various industries and applications. The specified chemical composition and heat treatment processes ensure the desired properties of the material, making it suitable for use in environments with high temperatures and corrosive conditions.
