    Co-efficient of thermal expansion and NIST

    Thanks Ed & Iain for your comments; I also found this http://www.eckelsengineering.com/ , although I haven't paid for it yet, so anyone that's used it would be good to hear from. I guess it is a computerised version of all the data mentioned in your link (which I have also used by the way!) ...

    Hi, I'm working on some tolerances after cool down, and have up until now been using CTE's; typically 17,3um/mK for 304SS, 16um/mK for 316SS, and 16,7um/mK fro BeCu I've been refining my design, and have been double checking with the NIST cryo materials page, where I have worked out expected...
