Properties and main applications

* Austenitic chromium-nickel-silicon steel with extra low carbon content. High corrosion resistance against highly concentrated nitric acid (80 – 99,5%) or nitric acid with additions of strong oxidiser. Resistant to intergranular corrosion up to 350 °C. * Components in the chemical industry, heat exchanger, columns and acid refrigerators, application temperature from -50°C up to 350°C (for transport and storage tanks max. 200°C).
