Deepfreeze – cryogenic treatment

Retained Austenite

The deep-freeze treatment of the workpieces serves primarily to achieve a reduction of retained austenite after hardening. Thus, in the final use of the workpieces, the dimensional change properties are positively influenced.


Loyal HMW partners know that we use the Christmas holidays every year to carry out maintenance and repair work.
We will therefore be closed again this year from 23.12.2023 to 01.01.2024.

Neither collections nor deliveries are possible during this period.
Last delivery: 22.12.2023

We will be back for you on 02.01.2024.
