Is carbon steel used for cryogenic tanks?

Carbon steel is not typically used for cryogenic tanks due to its poor performance at extremely low temperatures. When temperatures drop significantly, the mechanical properties of carbon steel can deteriorate, making it brittle and susceptible to fractures. For cryogenic applications, materials need to maintain their toughness and ductility at such low temperatures.

Instead, materials like stainless steel or specialized alloys are preferred for cryogenic tanks because they retain strength and flexibility in cold environments. These materials can withstand the stresses imposed by the contents within the tank, providing safety and reliability in storage and handling of cryogenic fluids. Thus, the choice of materials is critical to ensuring both the structural integrity and the safety of cryogenic tanks, leading to the conclusion that carbon steel is not suitable for this application.
