What are the key properties of Super Duplex Steel Sheets?

These sheets deliver exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride rich and acidic conditions. They also offer very high tensile and yield strength, excellent weldability, and longer service life compared to standard duplex grades.

Where are Super Duplex Steel Sheets commonly used?

They are widely used in offshore oil & gas platforms, chemical processing, marine engineering, desalination plants, heat exchangers, and pulp & paper industries. Their ability to withstand seawater, chlorides, and strong chemicals makes them a preferred material for critical applications.

What are the main advantages of using Super Duplex Steel Sheets?

The major benefits include double the strength of stainless steels, outstanding resistance to seawater and acids, cost effectiveness compared to nickel alloys, and excellent fatigue strength. They also provide long service life with reduced maintenance costs.
