Processing & assembly

Application

Valve in the exhaust of an engine with a turbo. This valve bridges the turbo and keeps it from building up excessive pressure if the engine is at high revs or is loaded more heavily.

Advantages

  • Heat-resistant and wear-resistant steel alloy
  • Minimal post-processing required
  • Big savings in material costs

Advantage of the CIREX casting process

Inconel alloys are extremely durable and heat-resistant. This makes the material suitable for applications in turbochargers with exhaust gasses reaching 800° C. Since Inconel alloys are difficult to process, as many precise tolerances as possible are cast beforehand. Very few or no mechanical post-processing steps are needed.
