AISI 329 Duplex Plate and 2304 Duplex Plate

Author : Steel 456 | Published On : 31 Mar 2026

Among the duplex stainless steel options, Aisi 329 Duplex Plate is often mentioned for its higher content of chromium and molybdenum which provides superior protection against pitting and stress corrosion cracking. Generally, this type of steel follows ASTM A240 standards and is available in thicknesses varying from 5 mm to 80 mm. It undergoes a solution annealing and pickling finishing process. The blend of ferritic and austenitic phases in the microstructure leads to a yield strength of more than 450 Mpa, thus making it apt for applications like pressure vessels, marine equipment and structural components.

Various purchasing options including pipingmaterial.sa, buyers from Riyadh, Dammam, and Jeddah look into major factors like PREN values, weldability and impact resistance before deciding on duplex materials. Authentic suppliers offer certificates such as EN 10204 3.1, conduct PMI testing and provide corrosion resistance data to confirm that their products meet the engineering standards of the world. Besides, for projects in the oil, gas and desalination sectors, material origin and surface finishing options like hot rolled or blasted plates are frequently considerations.

On the other hand, lean duplex variants are preferred when the primary considerations are lower cost and a level of corrosion resistance sufficient for the given environment. The reduced nickel content and composition optimization allow these materials to be used for structural and storage purposes in the industrial zone of Al Khobar. When roles for these materials are being defined, the respective engineers perform checks on parameters like tensile strength, elongation, and fabrication characteristics.

Among the aforementioned options, 2304 Duplex Plate is one of the most common choices because it has less alloy and performs well against chloride attacks. Through pipingmaterial.sa, real buyers get an opportunity to communicate with suppliers that offer 2304 Duplex Plate in different dimensions and certified for industrial applications.
