Material selection for Liquid Nitrogen

[naqin]

Hi,

I need some information, kindly provide:
what material of tank / vessel is recommended for the storage of liquid nitrogen.The expected Min. Design Temperature would be -320 Deg F.

Regards

One option is stainless. 304L is used for a lot of crygenic applications. There is a large CTE to work with, but there is no ductile/brittle trasition to worry about.

9% Ni steels and aluminum alloys (especially for tanks used in transport) are also used.

201 is cheaper than 304 and 9% nickel and tougher at cryogenic temperatures. It is the standard alloy for many cryogenic vessel manufacturers.
