Subzero Heat Treatment Machines

Subzero heat treatment machines are used in the hardening stage of some steel alloys in the heat treatment industry. It is a process step generally applied at minus degrees to reduce the amount of residual austenite and increase the martensitic transformation rate. As Vizyon Heat, we design and manufacture subzero heat treatment machines for cryogenic applications. We provide support to automotive, aviation and heat treatment companies that have a heat treatment line.
