Common Applications of Super Duplex 32750 Foil

Common Applications of Super Duplex 32750/32760 Foil

Super duplex stainless steel foil is a highly versatile material with excellent corrosion resistance, high strength, and superior toughness. It is ideal for use in environments that require these properties, and it finds many applications across various industries. This blog post will look at the common applications of super duplex 32750 foil.

What is Super Duplex 32750 Foil?

Super Duplex 32750 Foil is a high-alloyed, duplex stainless steel produced and designed for extreme corrosion resistance and strength. Its 25% chromium, 5% nickel, and 3.5% molybdenum composition give it unmatched corrosion resistance compared to stainless steel. Further additions of nitrogen enable even greater levels of chloride pitting resistance while maintaining strong mechanical properties that can be enhanced with cold working processes. This makes it ideal for many tough applications, such as in industrial piping systems or marine environments where the highest standards for corrosion protection are required. Super Duplex 32750 Foil is one of the most reliable and durable alloys, providing an excellent level when properly installed and maintained.

A Brief Look at the Common Applications of Super Duplex 32750 Foil

Oil and Gas Industry:

Due to its corrosion resistance and high-strength properties, the oil and gas industry relies heavily on super duplex foil. It is commonly used in offshore oil platforms, subsea pipelines, and other critical oil and gas infrastructure components. Since these structures operate in harsh environments, super duplex foil ensures maximum reliability and durability.

Chemical Processing:

Super duplex foil is also used in the chemical processing industry, exposed to highly corrosive substances. The foil can withstand the harsh chemical environment and provide superior protection against corrosion. It is commonly used in pressure vessels, heat exchangers, and other high-risk applications.

Desalination Plants:

Due to its exceptional corrosion resistance, desalination plants use super duplex foil in their heat exchangers. The foil ensures efficient heat transfer and longer service life, minimizing the need for replacements and maintenance. Its ability to resist corrosion from seawater is critical in ensuring the reliability and efficiency of desalination plants.

Heat Exchangers

Super Duplex 32750 foil is also commonly used in heat exchangers due to its exceptional corrosion resistance and thermal conductivity. The alloy can withstand high temperatures without losing its mechanical properties, making it an ideal material for these applications. Additionally, its excellent weldability allows for easy installation of the heat exchanger components.

Aerospace and Defense:

Super duplex foil is also used in the aerospace and defence industries due to its high strength and toughness. The foil is ideal for applications requiring strength and good formability, such as protective armour plating and missile casings. Its high strength-to-weight ratio makes it a preferred material in the aerospace industry.

Flue Gas Desulfurization (FGD) Systems

Due to its superior corrosion resistance properties, Super Duplex 32750 foil is also often used in flue gas desulfurization (FGD) systems. These systems are designed to reduce sulfur dioxide emissions from coal-fired power plants by removing sulfur compounds from the exhaust gases before they are released into the atmosphere. The alloy’s excellent strength and ductility make it well-suited for use in FGD systems, as it can withstand the high pressures present within these systems without compromising performance or safety.

Medical Industry:

Super duplex foil is used in medical applications requiring high biocompatibility or resistance to harsh chemicals. Devices such as pacemakers, artificial joints, and surgical instruments use super duplex foil because it can prevent infections and resist corrosion from bodily fluids.

Marine Applications

Super Duplex 32750 foil is also widely used in marine applications due to its superior corrosion resistance properties and ability to withstand harsh saltwater environments without losing its mechanical properties over time. The alloy is often used for boat hulls, propellers, mooring lines, anchors, deck hardware, and other components that must withstand saltwater exposure without corroding or deforming over time.

Food Processing Equipment

Super Duplex 32750 foil is also often used in food processing equipment due to its superior corrosion resistance properties and ability to withstand extreme temperatures without compromising performance or safety. The alloy’s excellent formability makes it ideal for tubing or piping within food processing equipment, as it can be easily bent into various shapes while maintaining its structural integrity over time. Additionally, its non-toxic nature makes contact with food products safe during processing operations.

Semiconductor Manufacturing Equipment 

 Super Duplex 32750 foil is frequently used in semiconductor manufacturing equipment due to its outstanding electrical conductivity properties and superior corrosion resistance capabilities. The alloy’s ability to resist oxidation at elevated temperatures allows it to be used safely within semiconductor manufacturing equipment without damaging sensitive components. Additionally, Super Duplex 32750 has a low coefficient of thermal expansion, which helps maintain accuracy when fabricating components with very tight tolerances.

Conclusion:

Super duplex foil offers properties that other materials cannot match, making it valuable for various industries. It finds applications in various fields, from oil and gas to medical devices, due to its exceptional corrosion resistance, high strength, and durability characteristics. Through continued research and development, its capabilities will only continue to expand, offering even broader applications in the future.
