Superalloy turbine wheel used for Locomotive and Marine turbocharger, turbine wheel be finished by integral casting. And casting method of turbine wheel is lost wax investment & vacuum casting, casting surface smoothness can meet Ra3.2μm-Ra1.6, production process of turbine wheel is Silica sol process. The blade thickness is 0.5mm. For turbine wheel, we can do the kinds of type: radial turbine wheel and axial turbine wheel.
The material of turbine wheel is superalloy Inconel713c. And all turbine wheel are subjected to stress relief heat treatment to imporve the mechanical properties of products. After heat treatment mechanical properties can meet:
| High temperature Tensile strength | ≥830MPa |
| Elongation | ≥3% |
|
Persistent creep tensile strength at high temperature |
≥225MPa |
| Persistent creep tensile strength of keeping time | ≥40H |
