Expert solutions to help you succeed
Cryogenic treatments of alloy steels have been claimed to significantly increase wear resistance and toughness through the interplay of three effects: completing martensitic transformation of retained austenite, promoting uniform precipitation of fine carbides, and imparting residual stresses. These treatments require specialized equipment that can cool materials with cold nitrogen down to as low as -300°F (-184°C), and warm them to ambient temperature, or in some cases as high as 1200°F (650°C) for tempering. Air Products can provide liquid nitrogen and supply systems for the full range of cryo-tempering applications.
