ASTM A790 Duplex 2507 UNS S32750 Super Duplex Stainless Steel Seamless Pipe

S32750, also known as Super Duplex 2507, is a highly corrosion-resistant stainless steel alloy that is often used in harsh environments. It combines both the properties of austenitic and ferritic stainless steels, offering excellent strength and corrosion resistance. While S32750 is a specific grade, there are other similar duplex stainless steels (like S32205) that might be used as alternatives depending on specific requirements. Understanding the slight differences in composition can help in selecting the best alloy for a given application.

S32750 exhibits low thermal expansion, making it an excellent choice for situations where components are subject to considerable temperature fluctuations. This property helps maintain dimensional stability.

Applications

1. Oil and Gas Industry: Often used for pipes in offshore platforms, subsea equipment, and chemical processing due to its corrosion resistance.

2. Chemical Processing: Utilized in reactors, heat exchangers, and storage vessels where exposure to aggressive chemicals occurs.

3. Marine Applications: Used in shipbuilding and marine infrastructure where saltwater exposure is a concern.

4. Desalination Plants: Employed in the infrastructure for seawater reverse osmosis systems because of its resistance to seawater corrosion.

5. Pulp and Paper Industry: Used in environments where chlorinated compounds are present.
