What are the key properties of Duplex Steel Plates?

These plates offer twice the strength of austenitic stainless steels, excellent resistance to stress corrosion cracking, good weldability, and long term durability. They also resist pitting and crevice corrosion, especially in chloride rich environments.

Where are Duplex Steel Plates commonly used?

They are widely used in oil & gas, chemical processing, desalination plants, shipbuilding, paper & pulp, and power generation industries. Their ability to perform under high pressure, seawater, and harsh chemicals makes them suitable for critical applications.

What are the main advantages of Duplex Steel Plates?

The advantages include high strength to weight ratio, superior corrosion resistance, long service life, and reduced maintenance costs. They are also tough and fatigue resistant, making them suitable for dynamic and heavy load applications.
