AMS 5536 Uses
AMS 5536 is used in a wide range of applications in various industries. Its high-temperature resistance and excellent mechanical properties make it suitable for jet engine parts, gas turbine components, industrial heat exchangers, and chemical processing equipment. It is also used to construct aircraft brake disks, landing gears, and other critical aerospace components.
AMS 5536 Hardness
The hardness of AMS 5536 varies depending on the heat treatment process used. Its annealed state has a Brinell hardness of around 170 to 200. However, heat treatment can increase its hardness to about 210 to 240. This increase in hardness can be achieved through a range of heat treatment processes, such as quenching and tempering or precipitation hardening.
AMS 5536 Heat Treatment
AMS 5536 can be heat-treated to improve its mechanical properties and increase its hardness. Quenching and tempering, for instance, involves heating the alloy to around 1975°F (1080°C), holding it at that temperature for a specific period, and then rapidly cooling it. This process can improve the alloy’s strength and toughness. On the other hand, precipitation hardening involves subjecting the alloy to a series of heat treatments, cooling, and ageing processes. This process can improve the alloy’s hardness and strength.
