Austenitic-ferritic stainless steels (duplex steels) are characterised by their excellent mechanical properties, particularly their high resistance to stress corrosion cracking. They are especially well-suited for seawater applications and in the chemical industry. Their excellent resistance to corrosion enables them to withstand a chloride medium, particularly under mechanical stress. This makes them superior to austenitic steels in many cases.

The increasing use of stainless steel hollow sections in load-bearing structures has created a demand for more high strength stainless steels. For example, Lean Duplex stainless steels have an excellent combination of strength and corrosion resistance. This enables a lighter, more durable and maintenance-free end product for demanding applications. By lowering total material weight, you also lower transportation and assembly costs, thus reducing environmental impacts. This makes Duplex stainless steel a real material of the future.

Superior Advantages of Austenitic Ferritic Duplex Stainless Steel Pipe & Tube :
