Duplex stainless steel plates are a type of stainless steel alloy that combines the benefits of ferritic and austenitic stainless steels. This two-phase microstructure provides superior resistance to corrosion, stress corrosion cracking, and erosion, making duplex stainless steel plates ideal for use in harsh environments such as offshore oil rigs and chemical processing plants.
At Om Steel, we offer a range of duplex stainless steel plate grades, including S31803, S32205, S32750, and S32760, each with its own set of mechanical properties and corrosion resistance. Our plates are available in a range of sizes and thicknesses to meet your specific needs.
In addition to their resistance to corrosion, duplex stainless steel plates also offer high strength, excellent toughness, and good weldability, making them suitable for use in a variety of applications.
Whether you need duplex stainless steel plates for oil and gas, chemical processing, marine engineering, or other industrial applications, Omsteel has the products and expertise to meet your requirements. We are committed to providing high-quality products and excellent customer service.
