Duplex Stainless Steel Plate

Duplex stainless steel is a type of stainless steel with both austenitic and ferritic structures. It has high strength, excellent corrosion resistance and resistance to stress corrosion cracking, and is widely used in marine engineering, oil and gas, chemical equipment and pressure vessels.

The high chromium, molybdenum, and nitrogen content endows the material with excellent resistance to pitting and crevice corrosion, making it particularly suitable for seawater and chemical environments.

The duplex microstructure provides higher yield strength, allowing for thinner materials under the same design conditions, thus reducing overall project costs.

Compared to traditional austenitic stainless steel, it offers greater resistance to stress corrosion cracking in chloride environments, improving equipment operational safety.

Raw Material Control
Using duplex stainless steel billets conforming to international standards, with strict control over the content of key elements such as Cr, Ni, Mo, and N.

Manufacturing
Through hot rolling, solution treatment, and pickling processes, we ensure stable duplex microstructure and uniform material properties.

Dimensioning
We support cutting, leveling, length cutting, and beveling to meet the needs of various engineering projects.

Quality Inspection
We conduct tests on chemical composition, mechanical properties, dimensional tolerances, ultrasonic flaw detection, and corrosion resistance to ensure a stable supply.

Marine Engineering
Used in seawater desalination equipment, offshore platform structures, and seawater pipelines to enhance resistance to seawater corrosion.

Oil & Gas
Used in pressure vessels, storage tanks, and transportation equipment to withstand high-pressure and corrosive media environments.

Chemical Equipment
Used in reactors, heat exchangers, and storage containers to extend equipment lifespan and reduce maintenance costs.

Power Energy
Used in flue gas desulfurization equipment and environmental protection systems to improve equipment corrosion resistance and operational stability.

Shipbuilding Industry
Used in ship structural components, deck equipment, and marine infrastructure to improve durability and safety.
