Pressure vessel steel for -57 F degree service
Pressure vessel steel for -57 F degree service
(OP)
I am looking for a suitable steel for a pressure vessel that will contain -57 F air. Any suggestions?
According to the ASME PVHO (Pressure Vessels for Human Occupancy) code, the steel needs to be charpy tested at -57 -50 = -107 F. I can't find any charpy data for this.
I think that a 300 series stainless would be exempt from the charpy test but I would like to find a less expensive alternative to stainless.

ASME SA 203
or ASME SA 353. However, this is probably overkill for your intended service.

Not all 516*70 material will get down that low and should use SA-350-lf-3 flanges.
My choice if I were able to choose materials...would be
300 series stainless. exempt from impacts.
a-203-e/ a-350-lf3 is another choice that would be easy to make impact values
