EN 10217-7 X6CrNiTi18-10 Solution-Annealed Austenitic Steel – Corrosion-Resistant & High-Temperature Performance

The austenitic steel X6CrNiTi18-10 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 400 °C) also in the welded condition.
