EN 10217-7 X2CrNi18-9 Solution-Annealed Austenitic Steel – High-Performance Tubing

The austenitic steel X2CrNi18-9 is available in the solution annealed condition. Welded circular tubes of this steel are used for compression load and for corrosive load at room temperature, low temperatures and elevated temperatures. The material is resistant to intercrystalline corrosion (up to 350 °C) also in the welded condition.
