Diameter 350mm turbojet engine parts supealloy turbine wheel casting
Turbine wheel belongs to turbojet engine parts,The material of turbine wheel is K424, K424 material belongs to high temperature alloy, this material can operate at temperatures above 1,000 degrees Celsius. The diameter of turbine wheel is φ350mm. The turbine wheel is one casting instead of split casting. The casting surface smoothness of turbine wheel can meet Ra3.2μm and casting process is Silica sol process, Casting method is investment vacuum casting.
The below table show mechanal property of turbine wheel:
| State | Tensile property(20℃） | Medium temperature persistence performance（975℃） | |||
| αb(MPa） | δ5（%） | Ψ（%） | α（MPa) | t(h) | |
| casting state | ≥830 | ≥5 | ≥7 | 196 | ≥40 |
