A240 S32750, also known as 2507 Super Duplex Stainless Steel, is a high-performance material designed for demanding environments where superior mechanical strength and corrosion resistance are crucial. Developed through advanced metallurgical techniques, this steel plate offers a unique combination of properties that make it a preferred choice in various industries.

Chemical Composition

---------

The chemical composition of A240 S32750/2507 Super Duplex Stainless Steel Plate is carefully balanced to ensure optimal performance. It contains approximately 25% chromium, 4% molybdenum, and 7% nickel, along with controlled levels of carbon, silicon, manganese, phosphorus, sulfur, and nitrogen. This composition provides the steel with exceptional corrosion resistance, especially against chloride-containing environments.

Mechanical Properties

-----------

The mechanical properties of A240 S32750/2507 Super Duplex Stainless Steel Plate are remarkable. It exhibits high yield strength, typically twice that of austenitic stainless steels, and excellent tensile strength ranging from 90 ksi (620 MPa) to 110 ksi (800 MPa). The steel also possesses good ductility, with an elongation of at least 25%, and high impact strength, ensuring reliable performance in challenging conditions.

Heat Treatment

-------

A240 S32750/2507 Super Duplex Stainless Steel Plate undergoes a strict heat treatment process to achieve its desired properties. The steel is heated to a temperature range of 1050-1150°C for solid solution annealing, followed by rapid cooling to room temperature. This process eliminates intergranular phases and sulfides, restoring the corrosion and mechanical properties of the steel. Optionally, a tempering treatment may be performed to further enhance the material's toughness.

Dimensional Range

---------

A240 S32750/2507 Super Duplex Stainless Steel Plate is available in various sizes to meet specific project requirements. Cold-rolled plates range in thickness from 0.3mm to 6mm, while hot-rolled plates are available from 3mm up to 200mm thick. The standard plate dimensions include 1000×2000, 1219×2438, 1500×3000, and larger sizes for hot-rolled plates. Custom sizes can also be produced upon request.

Impact Testing

--------

A240 S32750/2507 Super Duplex Stainless Steel Plate undergoes rigorous impact testing to ensure its suitability for demanding applications. The steel exhibits high impact energy absorption, with a minimum impact energy of 74 ft-lbs (100 J), ensuring reliable performance in low-temperature environments and under sudden loading conditions.

Primary Applications

----------

A240 S32750/2507 Super Duplex Stainless Steel Plate finds widespread use in various industries due to its superior properties. In the oil and gas industry, it is utilized in offshore platforms, heat exchangers, subsea equipment, and fire protection systems. The chemical processing industry relies on its corrosion resistance for equipment, vessels, and pipelines. The steel is also used in desalination plants, high-pressure RO systems, and seabed pipelines. In the energy sector, it plays a crucial role in FGD systems, industrial scrubbing systems, and absorption towers. Additionally, its applications extend to the construction of bridges, tunnels, and high-rise buildings in coastal and industrial areas.
