AMS 5654 Uses

Due to its outstanding physical and mechanical properties, AMS 5654 bars is commonly used to produce specialized aircraft, propulsion systems, and marine parts. It is also popular for petrochemical plants since it can resist various acids and chemicals exposed during production. The alloy has also displayed remarkable resilience in producing exotic supercars, making them last longer and minimizing their degradation process.

AMS 5654 Hardness

AMS 5654 has a hardness ranging around 50 HRC. This hardness level enhances wear and tear resistance, efficiently resisting damage from high-speed sand and abrasive particles.

AMS 5654 Heat treatment

AMS5654 is a special alloy that requires proper heat treatment. The alloy should never be exposed to extreme heat since the excessive temperature can cause it to warp or create residual stress. Heat treatment of AMS 5654 can be achieved by following the AMS 2759 specification. This specification involves the process of uniform heating and controlled cooling to help the material maintain a stable form.


AMS 5654 material is not your average steel alloy. It is a material that can withstand extreme temperatures and corrosive substances present during aerospace, marine, and petrochemical production processes. Its unique properties make it ideal for specialized aircraft, cars, propulsion systems, and desalination plants. It can resist damage from abrasive particles and has a relatively high hardness, making it more durable than many alternative materials. In addition, it is crucial to pay attention to proper heat treatment of the alloy, which will ensure that it maintains its robustness and stability during service.
