Subzero Treatment

General Information

Since the martensite transformation temperatures of the materials whose surface is enriched in carbon and nitrogen after the carburizing and carbonitration processes fall below room temperature, a certain amount of residual austenite is formed in the materials after the transformation. In order to remove this residual austenite, the materials must be deep-cooled.

There are 2 deep cooling cabinets in our company. Cryogenic processes can be performed at very low temperatures in the deep cooling cabin using liquid nitrogen.
