nitrogen for quick cooling & Parts Freezing
Rapidly improve your metal properties
Linde offers a sub-zero treatment – a cryogenic application— that is applied to metal parts following a normal heat treatment process. The use of liquid nitrogen to cool down parts works by transforming retained austenite into martensite and by precipitating fine carbides. As a result, the sub-zero treatment benefits include:
- Improved hardness
- Improved dimensional stability
- Increased wear resistance
- Extended lifetime
The change in temperature profiles make this method the ideal fit for the demanding requirements of aviation, aerospace and automotive industries.
In addition to liquid nitrogen, Linde offers specially engineered cryogenic cooling equipment. The CRYOFLEX® freezers are available in four off-the-shelf freezers – cabinet, box, tunnel and further continuous models. Complementing this standard offering, Linde also provides customized models in various standard and tailored sizes to meet your specific efficiency, heat loss and gas consumption needs.
