EN 10222‑5 X5CrNi18‑10 Solution Annealed (+AT): High‑Performance Austenitic Stainless Steel

Material X5CrNi18-10 is the standard type of the austenitic chrome-nickel-steel. To the comparable trademark X 5 CrNi 18 10 acc. to DIN 17440 : 1985-07 applies: the material shows high corrosion resistance but no resistance to intercrystalline corrosion in sensitized condition as well as favorable workability. The steel is suitable for mirror finishing and very good cold and warm formable. Application for welded parts in chemical apparatus engineering, food and milk industry, for household appliances, in breweries, in architecture and vehicle construction as well as for pumps, compressors, fittings, in water and slightly contaminated sewages. In pressure vessel construction up to 300 °C applicable, above 300 °C. subject to authorization. Application temperature: -200 to 550 °C. X5CrNi18-10 is used in construction trade for decorative purposes in exterior and interior architecture, e.g. roof and wall elements, facings, washing facilities, washbasins in toilet facilities, for doors and windows. This material is approved for load-bearing components.
