ASTM A182 F53 Equivalent S32750 Duplex Stainless Steel Plate Thickness 1.0 - 50.0mm

S32750 Duplex Stainless Steel Plate Product Information​

1. Product Overview​

The S32750 duplex stainless steel plate, also known as 2507 in some cases, is a high - performance super duplex stainless steel product. It features a balanced microstructure of approximately 50% austenite and 50% ferrite, which endows it with a unique combination of properties.​

2. Key Properties​

2.1 Mechanical Properties​

• High Strength:​

• Tensile strength: ≥750 MPa. This high tensile strength allows the S32750 plate to withstand heavy loads and mechanical stress in various applications.​

• Yield strength: ≥550 MPa. It can resist plastic deformation under high stress conditions, ensuring the stability and reliability of structures.​

• Elongation: ≥25%. Despite its high strength, it still maintains good ductility, which is beneficial for forming and shaping processes.​

• Good Toughness: It exhibits excellent notch ductility at ambient and sub - zero temperatures (down to - 50 °C), which means it can resist brittle fracture even in cold environments.​

2.2 Corrosion Resistance​

• Exceptional Pitting and Crevice Corrosion Resistance:​

• With a high chromium content (about 25%) and a significant molybdenum content (about 3 - 5%), the S32750 plate forms a stable passive film on its surface. This film effectively prevents the initiation and growth of pits and crevices in corrosive media.​

• The pitting resistance equivalent number (PREN) is typically ≥40.0, which is much higher than that of many common stainless steels. For example, compared to 316L stainless steel with a PREN of around 26, S32750 shows much stronger resistance to pitting corrosion.​

• Outstanding Stress Corrosion Cracking Resistance: In environments containing chlorides and hydrogen sulfide, the S32750 plate has a remarkable ability to resist stress corrosion cracking. This makes it suitable for applications in harsh chemical and marine environments.​

• Good Uniform Corrosion Resistance: It demonstrates excellent resistance to corrosion in a wide range of acid, alkali, and salt solutions, ensuring long - term durability in different chemical media.​

4. Applications​

4.1 Oil and Gas Industry​

• Pumps, Valves, and Chokes: The high strength and excellent corrosion resistance of S32750 make it ideal for manufacturing pumps, valves, and chokes, which are exposed to corrosive oil and gas fluids.​

• Pipework and Flanges: In pipelines and flanges used for transporting oil and gas, especially in offshore platforms where the environment is extremely harsh, S32750 plates can ensure long - term integrity and reliability.​

• Connectors and Manifolds: S32750 is suitable for connectors and manifolds, which need to withstand high pressure and corrosive media.​

4.2 Chemical Processing​

• Reactors and Pressure Vessels: In chemical plants, reactors and pressure vessels made of S32750 can handle highly corrosive chemical reactions and high - pressure conditions.​

• Heat Exchangers: The good heat transfer performance and corrosion resistance of S32750 make it a preferred material for heat exchangers in chemical processes, ensuring efficient heat transfer and long - service life.​

4.3 Marine Applications​

• Shipbuilding: S32750 plates are used in shipbuilding, especially in areas such as hulls, decks, and seawater - handling systems, due to their high resistance to seawater corrosion.​

• Offshore Structures: For offshore platforms, piers, and other marine structures, S32750 provides the necessary strength and corrosion resistance to withstand the harsh marine environment.​

4.4 Other Applications​

• Paper and Pulp Industry: In equipment such as digesters, bleach plants, and material handling systems, S32750 plates can resist the corrosive chemicals used in the paper - making process.​

• Food and Beverage Industry: Where high - hygiene standards and corrosion resistance are required, S32750 can be used in equipment and pipelines, ensuring product safety and equipment durability.​

• Desalination Plants: S32750 is suitable for components in desalination plants, such as heat exchangers and pipelines, as it can resist the corrosive effects of seawater and the chemicals used in the desalination process.​

5. Product Specifications​

• Thickness: Available in a wide range, typically from 0.5 mm to 80 mm, to meet different application requirements.​

• Width and Length: Customizable widths and lengths are available. Common plate sizes include 12000 x 2000 mm, 12000 x 2500 mm, 12000 x 3000 mm, etc. For special orders, we can also provide non - standard sizes according to customer needs.​

6. Quality Assurance​

All S32750 duplex stainless steel plates are produced in accordance with international standards such as ASTM and EN. Each batch of products undergoes strict quality inspection, including chemical composition analysis, mechanical property testing, and corrosion resistance testing. We can provide detailed mill test certificates and inspection reports to ensure product quality and traceability.​

7. Packaging and Delivery​

• Packaging: The plates are carefully packaged to prevent damage during transportation. They are usually wrapped in waterproof paper and plastic film, and then strapped with steel bands. For large - quantity orders, they may be packed in wooden crates.​

• Delivery: We cooperate with reliable logistics partners to ensure fast and safe delivery. Delivery time depends on the order quantity and destination, but we will strive to meet the agreed delivery schedule as much as possible.
