Uses
Inconel 625 is used in a variety of extreme-temperature applications. It is a popular choice in aerospace applications due to its corrosion resistance and high-temperature strength. Other common applications for Inconel 625 include oil and gas, chemical processing and pollution control.
In the oil and gas sector, Inconel 625 is often used in the production of specialized valves, fittings, and fasteners. This metal is ideal for use in valves, as it is resistant to corrosion and can stand up to the rigors of high-temperature oil production. Additionally, its exceptional strength and durability make it ideal for high-pressure applications.
In the field of chemical processing, Inconel 625 is often used to manufacture valves, piping, and flanges. This metal is also highly resistant to corrosion, and offers a degree of resistance to hot hydrocarbon gas mixtures. Additionally, Inconel 625 offers greater crack resistance than other super alloys, making it a more reliable choice in the production of piping and flanges.
Conclusion
Inconel 625 is a superalloy of high chromium and nickel concentration that offers a high degree of protection against corrosion and oxidation. It is primarily used in extreme-temperature and harsh environments, such as oil and gas, chemical processing and pollution control, due to its resistance to corrosion and excellent mechanical strength. It is commonly used in the production of specialized valves, fittings, and flanges.
