Stainless steels with an austenitic structure are characterised by an excellent combination of corrosion resistance, Formability and durability. For this reason, they are used in various fields of application ranging from household appliances to the use in the chemical industry. Austenitic Steels are also known as chromium-nickel steels as chromium and nickel are the main alloying elements.
Super Austenitic Steels are very high-alloyed stainless steels. Compared to the common austenites, they show higher portions of the alloying elements chromium and nickel or also molybdenum. Super austenitic steels are therefore particularly suitable for applications where there is a very high risk of corrosion.
