Thanks

UNS N04400 will do -196 Deg C.

RE: Inconel 625 Low temp service

Sorry this is rather fractured.
I have always found great difficulty getting negative temperature properties for metals unless they have been specifically designed for that purpose i.e. 17.4 ph 1150MM.
 In the years I have been in Cryogenics we have always had to approach the manufacturer for more information.
The physical property testing at these temperatures is obviously a lot harder to under take a great deal more expensive for what must be seen as a minority of users.

RE: Inconel 625 Low temp service

Cryogenic material properties are available online at NIST:
http://cryogenics.nist.gov/MPropsMAY/material%20properties.htm

And for fluid properties:
http://webbook.nist.gov/chemistry/fluid/

The best set of data I've found is "Cryogenic Materials Data Handbook" Fred R Schwartzberg et al  I believe you can get a copy online here:
http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=AD0420407

Note that none of these resources actually has Inconel 625, though they have other types of Inconel.
