304 Stainless Steel Cryogenic Performance

1. What is the minimum cryogenic temperature 304 can withstand? It retains toughness down to -270°C (liquid helium temperature).

2. Does 304 become brittle at low temperatures? No, its austenitic structure ensures ductility and toughness even at extreme cold.

3. Can 304 be used in LNG equipment? Yes, for non-core components like storage tank liners and transfer pipelines.

4. How does cryogenic exposure affect 304's mechanical properties? It retains tensile strength and elongation without significant degradation.

5. Is 304L better than 304 at cryogenic temperatures? Both perform well, but 304L has slightly higher ductility at extreme low temperatures.
