Cryogenic carbon steel
Cryogenic carbon steel is subjected to below-zero heat treatments to change its microstructure and achieve some improvements, such as increased resistance to corrosion and wear and greater dimensional stability.
When steel is exposed to cryogenic temperatures, its mechanical behaviour changes, and resilience, among others, decreases. Changes vary depending on the grade, and in materials such as ferritic steel there are remarkable changes in several mechanical properties, such as hardness, resilience, and wear resistance.
During the cryogenic treatment, both the process of exposure to the cold and the later return to room temperature must be very gradual and controlled to prevent stress in the steel that leads to cracks and other undesired effects.
Cryogenic carbon steel is usually harder and more resilient than other materials. This results in a high degree of resistance and durability, and it is often used in the automotive industry.
