In industries where strength, corrosion resistance, and durability are non-negotiable, Duplex Steel Plates and Super Duplex Plates stand out as the preferred choice. From offshore oil rigs to chemical plants and desalination facilities, these materials offer unmatched performance under the harshest conditions. At Duplex Steel and Engineering Company, we specialize in manufacturing and supplying premium-grade Duplex Stainless Steel Plates that meet the highest international standards and exceed client expectations.

Whether you are a project manager looking for large volumes or a fabricator in need of custom-sized plates, we have the capability and expertise to deliver what you need, when you need it.

What Are Duplex Steel Plates?

Duplex Steel Plates are made from duplex stainless steel—a material known for its dual-phase microstructure combining austenitic and ferritic steel. This unique structure provides:

• High strength (almost twice that of regular stainless steel)

• Superior resistance to stress corrosion cracking and pitting

• Excellent weldability and formability

• Long service life even in aggressive environments

These properties make duplex plates an ideal choice for applications in industries such as marine engineering, chemical processing, pulp & paper, and oil & gas.

Super Duplex Plates – Performance at the Highest Level

When even greater corrosion resistance and mechanical strength are required, Super Duplex Plates are the solution. With a higher molybdenum and chromium content than standard duplex grades, super duplex steel can withstand extreme pressure and corrosive environments like seawater, acidic solutions, and high-chloride applications.

At Duplex Steel and Engineering Company, we offer Super Duplex Plates in various grades such as:

• UNS S32750

• UNS S32760

These plates are perfect for use in subsea systems, offshore platforms, pressure vessels, heat exchangers, and more.

Duplex Stainless Steel Plate – Precision Engineering for Demanding Projects
