DIN 17440 Grade X3CrTi17 soft annealed (+A)
DIN 17440 Grade X3CrTi17 soft annealed (+A) introduction
The for pressure vessels approved material X3CrTi17, mat. no. 1.4510, has an similar corrosion behaviour like the X6Cr17 (1.4016). The steel is resistant to intercrystalline corrosion in the delivery condition and also in the welded condition. It is higher resistant to stress corrosion in hot lyes and weak chloride containing waters. Because of the Ti-content there is no danger for intercrystalline corrosion after welding. Thats why the steel is not high polishable. According DIN 17440 : 1996-09 it is used for flat products and rods and drawn wire and acc. DIN 17441 : 1997-02 for cold rolled strips and slit strips for pressure vessels.
For the application acc. DIN 17440 : 1985-07 (X 6 CrTi 17) resp. acc. DIN EN 10088-1,-2,-3 : 1995-08 (X3CrTi17) applies: application for welded parts in washing machines (lye bins) and partially in the chemical apparatus engineering (weak acids), in the milk industry, food industry, brewery industry, textile industry and cosmetic industry.
