A cryogenic treatment (190°C/ -310°F) lasting more than 24 hours provides the treated parts with very high impact, corrosion and wear resistance, while giving them a useful life 2 to 5 times longer.
These treatments are particularly recommended for martensitic stainless steels, tool steels and parts working at high temperature and/or subject to wear.
Cold Treatment (deep freeze)
In the modern metallurgical industry, cold treatment (-85°C / -120°F) of hardened steels is largely used to transform the retained austenite into martensite. With this additional treatment, we can obtain the maximum characteristics of the treated material. In addition, the dimensional stability of the parts is greatly improved.
