EN 10222-5 Grade X2CrNiMo17-12-2 – Solution Annealed Steel for High-Performance Corrosion Resistance
Trademark X2CrNiMo17-12-2 is a modification of steel 1.4401. To the comparable DIN-make X 2 CrNiMo 17 13 2 acc. to DIN 17440 : 1985-07 applies: The material shows high resistance to non-oxidizing acids and chloride-containing media. It is suitable for mirror finishing and very well cold formable. Its corrosion properties are still improved due to the lowered C-content. This material is resistant to intercrystalline corrosion also in sensitized condition. Application in chemical apparatus engineering as well as in cellulose, textile and pharmaceutical industry and in sewage plants. It is approved for pressure vessel construction up to 400 °C., beyond it subject to authorization.
