Steel processing

The common processes for steel production and processing are associated with very high temperature levels. However, cold is required for some finishing processes, especially for transforming residual austenite after heat treatment. After annealing, the steel is cooled to -80 to -110 °C to bring about a specific structural change. This process is used to produce highly stressed steels for knives and tools, among other things. L&R plans the corresponding refrigeration technology.
