Austenitic stainless steel is most commonly used stainless steel grade due to its many benefits. Austenitic steel provides excellent formability and weldability. It is a highly corrosion resistant, maintenance free material that offers toughness at low temperatures and sustains its mechanical values even when the temperatures rise high. Austenitic steel grades give a 30-minute fire resistance without any additional fire protection. STALA offers austenitic grades also in high-strength classes.

Austenitic stainless steel tubes

Austenitic stainless steel has been used already many hundreds of years. It’s the well-known and most used stainless steel due to it’s many benefits.

Advantages of austenitic grades:

  • Excellent formability
  • Excellent corrosion resistance
  • Toughness at low temperatures
  • Good weldability
  • Fire resistance

We offer large range of austenitics stainless steel square and rectangular tubes in various metric and imperial sizes. Roll-formed and press brake austenitic square and rectangular hollow sections are available in various dimensions up to 300x300x12 mm and 400x200x12 I 12x12x0.500 inch and 16x8x0.500 inch. Standard length is 6m.

Various tailoring solutions available.

Use our high-strength hollow sections

STALA350  and STALA500 high-strength classes in austenitic stainless steel have multiple benefits. With structures’ higher strength, you will gain remarkable structural weight savings.

STALA500 and high-strength austenitic material grade EN 1.4318 / 301LN

Depending on tube size, high-strength austenitic material grade EN 1.4318 I 301LN is now available in strength class STALA350 and STALA500. These materials combine the best features of austenitic stainless steel –  high level of corrosion resistance and toughness and excellent formability and weldability – with lighter weight and lower price. Sustainable, safe, and cost-effective – totally revolutionary!

Roll-formed and press brake austenitic square and rectangular hollow sections

We also offer many tailoring options including custom-made dimensions, cut to length, laser cutting, surface finishes, specialty austenitic steel grades, and ready-to-assemble kit packages.
