| 1) Remark: Chemical composition: DIN 17851 TiAl6SnZr4Mo2Si with the material number 3.7145 is a titanium alloy with alpha + beta-structure. The material was developed for the use at higher temperatures and is relatively stable up to 550 °C. Creep strength and creep strength depending on time are better and the susceptibility to hot-salt stress cracking corrosion is lower than with the material TiAl6V4. The corrosion behaviour is similar to that of the material TiA6V4, and there is far-reaching corrosion-resistance to strongly oxidizing acids, alkali lyes, sea water, moist chlorine gas etc. Processing properties: Formability: limited (cold forming is only possible to a limited extent) Weldability: limited (less well weldable than TiAl6V4, the electron-beam welding is well suitable, the suitability of tungsten inert-gas welding is limited) Application: 3.7145 is particularly applied for compressors in engines, e.g. discs, blades, impellers and seals as well as for valves in automobile engines. |
