Incoloy 825 or Inconel 625 is meant for high temperature creep service use. For cryogenic service it is not required and depending on negative temperature side you can use standard austenitic or Duplex SS regards DM

Duplex SS is not suitable for low temperature, DSS can only be used to minus 51 degree C. SS304 or SS316 are more suitable for cryogenic temperature. If minimum temperature is in the range of -46 to -85 degree C then A333 gr.6 and Gr. 3 are more suitable materials. Jagdish Gill

Generally I fully agree with Jagdish for low temperature material selection. Ahmed, If you would like to use Incoloy 825 or Inconel 625 for other purpose (i.e., corrosion, batch operation, etc.) as well, you can use them up to -198 deg.C. thomaseun@shaw.ca (for further discussion)

The suitable material for cryogenic services are S.S 304 & S.S.316.We have used these two materials in our argon olant. masoud
