Exceptional Strength and Durability

Super Duplex S32750 plates are designed to withstand high mechanical and environmental stress. With a minimum tensile strength of 800 MPa and yield strength of 550 MPa, they remain robust even under significant pressure or exposure to harsh chemicals. The alloys blend of elements provides reliable toughness and reliability, ideal for long-term use in critical infrastructures.

Unsurpassed Corrosion Resistance

Engineered for the utmost performance, S32750 plates provide exceptional resistance to pitting, crevice, and stress corrosion cracking. This makes them well-suited for applications exposed to aggressive environments such as seawater, desalination plants, and the oil & gas sector, ensuring extended service life and lower maintenance requirements.

Customizable Applications and Finishes

These plates can be manufactured to virtually any length, width, thickness, and finish, including mill, sheared, brushed, or polished edges. Their formability, moderate machinability, and excellent weldability make them versatile for use in pressure vessels, structural components, and heat exchangers. Custom sizes and surface finishes are available on request to meet diverse project needs.

FAQs of Super Duplex Steel S32750 Plates:

Q: How are Super Duplex Steel S32750 Plates processed and finished?

A: Super Duplex S32750 plates are produced using hot rolled or cold rolled techniques and can undergo additional treatments like pickling or polishing. They are available with different edge finishes, such as mill or sheared edges, and can be supplied uncoated or coated as required by the application.

Q: What advantages do Super Duplex S32750 Plates offer in corrosive environments?

A: These plates provide excellent resistance to pitting, crevice, and stress corrosion cracking due to their high chromium, nickel, and molybdenum content. This makes them especially beneficial for use in seawater systems, chemical processing, and desalination plants where corrosion resistance is crucial.

Q: When should Super Duplex S32750 Plates be used over standard stainless steel plates?

A: S32750 plates should be chosen when both high mechanical strength and superior corrosion resistance are needed. They outperform standard grades in harsh environments involving chlorides or high pressures, making them ideal for the marine, petrochemical, and oil & gas industries.

Q: Where can Super Duplex Steel S32750 Plates be applied?

A: These plates are primarily used in chemical processing, petrochemical plants, offshore oil & gas installations, desalination plants, and marine engineering. They are also suitable for pressure vessels, heat exchangers, and structural components in challenging environments.

Q: What are the recommendations for storing Super Duplex Steel S32750 Plates?

A: To prevent surface corrosion and maintain quality, it is recommended to store these plates in dry, covered conditions away from moisture and corrosive agents until installation or further processing.

Q: How are custom sizes and dimensions handled for S32750 plates?

A: Plates can be cut and supplied in standard lengths (2000 mm, 2500 mm, 3000 mm) or in custom dimensions as per project requirements. Thickness can range from 2 mm up to 100 mm, making them adaptable for a wide variety of industrial uses.
