3.7185 (DIN 17864 : 2012-03) TiAl4Mo4Sn2 3.7185 DIN 17864 : 2012-03 DIN 17864 : 2012-03 replaced by DIN 17864 : 2026-03 Replaced Germany TiAl4Mo4Sn2 TiAl4Mo4Sn2 2.3 1)
1) Remark: Chemical composition: DIN 17851 TiAl4Mo4Sn2 with the material number 3.7185 (see also TiAl4Mo4Sn2, material number 3.7184 according to the Werkstoff-Leistungsblatt der Deutschen Luftfahrt WL 3.7184) belongs to the hardenable alpha + beta-titanium alloys with high strength at room temperature and good creep resistance up to about 400 °C. Owing to the Mo-content that spreads the alpha + beta field, the material has a good lubricating quality. Furthermore, it possesses a good through-hardening with greater thicknesses (up to 150 mm), too, and good strength properties up to about 400 °C. The susceptibility to stress cracking corrosion is distinctly lower than with the materials TiAl6V4 and TiAl6V6Sn2. Apart from that, the corrosion behaviour is similar to that of the material TiAl6V4. Processing properties: Formability: limited (cold forming), good (hot forming) Weldability: not suitable for welding Application: Typical applications are compressor rotor discs, compressor blades, undercarriage components, structure components.
