RE: Steel for Cryogenic Containers

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dr. Sinha:

I would use an ASTM A240 Type 304 Stainless steel for the liner and any
material exposed to cryogenic temperatures.  Use whatever material and
thickness you need for the insulation.  Then a structural outer shell of
ASTM A36 plate.  Use spacers of the 304 stainless.

I would ask for confirmation to this inquiry by Steve Meier for
verification.  He monitors this list, and has much more experience in this
area than I do.

Good Luck,

Thanks for your very prompt response.  I will really apprecaite if 
you can send me the details of ASTM specs.  I really can't check 
with the local fabricators' claims unless I know more about the 
appropriate materials. 

Thanks in advance.
