IN738 powder applications by industry
| Industry | Typical parts | Why IN738 | Specify in your RFQ |
|---|---|---|---|
| Gas turbine blades and vanes | Hot-section parts originally cast in IN738 | High creep strength at turbine temperatures | Crack-susceptibility mitigation, HIP, heat treatment, NDE |
| Repair by DED | Blade tip and vane repair | Matches the parent cast alloy | Base metal, preheat, post-repair heat treatment and inspection |
Designations
- IN738
- Alloy 738
- K438
K438 is the Chinese designation closest to IN738. State whether you need standard or low-carbon (LC) chemistry, because carbon affects cracking and grain-boundary strength.
