Composition and Properties:

• Corrosion Resistance: Nickel alloys provide excellent corrosion resistance, especially in environments like seawater, hydrofluoric acid, sulfuric acid, and alkalis. This makes them ideal for use in chemical, oil and gas, and marine applications.
• High-Temperature Performance: They can maintain their strength and toughness at high temperatures, making them suitable for high-temperature applications.
• Wear Resistance: Nickel alloys also exhibit good wear resistance, which is crucial for the longevity of trunnion components that are subject to movement and mechanical stress.

Applications:

1. Oil and Gas Industry: For controlling the flow of crude oil, natural gas, and in refining processes.
2. Chemical Processing: In valves that manage corrosive substances and extreme temperatures.
3. Power Generation: In the control systems of coal, gas, and nuclear power plants.
4. Marine Applications: For sea water systems, naval ships, and offshore platforms where corrosion from salt water is a concern.

Alloys Used:

• Inconel (e.g., 625, 718): Known for high strength and excellent corrosion resistance in a wide range of acidic and high-temperature environments.
• Hastelloy (e.g., C-22, C-276): Offers outstanding corrosion resistance in the harshest environments such as chemical processing environments.
• Monel (e.g., 400, K-500): Excellent for sea water applications due to its resistance to corrosion.
