Heat treatment

Excellent in-house heat treatment facilities to ensure that the required mechanical properties required are met

H.I. Quality Steel Castings Ltd has a total of 6 heat treatment furnaces. All have programmable controllers and continuous reading thermocouples.

Each heat treatment cycle has parameters defined by programmable controllers reading directly from calibrated thermocouples. Continuous chart reading and digital data logging provides a complete heat treatment history and full traceability for each casting.

The microstructure is checked after each heat treatment cycle, and verified by our team of qualified metallurgists. Images are stored on our heat treatment database completing the full traceability of every component through the heat treatment processes.
