Austenitic Stainless Steels | Mannesmann Stainless Tubes

Corrosion resistant stainless steels

The category of austenitic corrosion resistant stainless steels primarily includes materials with higher alloy content (e.g. nickel, chrome and molybdenum). They are resistant to different types of corrosion caused by wet chemical influences, and are still able to maintain an austenitic face-centered cubic matrix. This creates a range of highly versatile stainless steels.
