The two data points mentioned above will work. They are from an actual graph of Young's Modulus in tension for Austenitic stainless steels. At 0 deg C,this is 32 deg F and at 60 deg C, this is 140 deg F. You can interpolate your specific values between these temperatures (there is little to no change in Modulus between 32 and 70 deg F).
I also have a bunch of good data for E vs temp.
The problem that I have is that differences in published E values are huge (+/-10%).
If you really need to know, then you need to make some measurements yourself. Most published data is looking at large ranges.
The way that your parts are made and the exact composition will have an impact down at this level.

shows 434ppm/degC, so the data is not 10% but 300%. Strange, as Young's is one of the more stable, process-resistant, alloy-resistant properties of metal...
The Code info is way too rough for this application. There is very good data on spring wire, but the modulus is different for wire than for other product forms so you may not want to use it.
