Lean Duplex and Duplex stainless steel tubes

High strength tubes for the most demanding applications  

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.  

Lean Duplex and Duplex materials are ideal for oil & gas, on-/offshore, construction, transportation and process industries, as well in applications where high strength, good corrosion resistance and low life cycle costs are needed.  

Superior advantages of Lean Duplex and Duplex material properties: 

• High strength enables lighter constructions
• Excellent corrosion resistance
• Improved stress corrosion cracking resistance
• Steady price level year after year based on low nickel content (1-2%)  


Material grades:

  • S32101
  • S32202
  • S32304
  • S32205 (2205)

Other material grades by request, please contact our sales for more information!

Stalatube expertise with Lean Duplex and Duplex material

Stalatube was one of the first companies on the market to start producing hollow sections made from Lean Duplex grades. These material grades were found to be fit for demanding structural applications. Stalatube has over ten years of experience in manufacturing and delivering Lean Duplex stainless products for different applications.
