total thermal expansion for pipe ASTM B444 UNS N06625

Hi,
I have some problems with material ASTM B444 UNS N06625 regarding to thermal expansion
When i open ASME B31.3 Table C-1, UNS N06XXX seris ( page 211-ASME B31.3-2006)i sew that the Total Thermal Expansion is only valid from 70 degree F above

How can we find total thermal expansion for this material with -115 degree C (~ -175 degree F) which is not in the table?

When we input the data in Caesar II with T=-115 degree C, using ASME 31.3, material Is ASTM B444 then "Start Run", Caesar shown error 60E:
"The temperature is outside the allowed range for this material".

Can anyone give more advices for this matter?
Thanks

Perhaps other piping Codes may offer a value. Or try Google.
Once you get a coefficient, you can either update the C2 material database or simply enter the coefficient in the temperature field. Entries in the temperature field will be considered as thermal strain rather than temperature if the entered value is less than 0.5. Read the Help.

Thanks Dave Diehl,
I am using Caesar II V5.10 build 080512
Checking coefficient for ASTM B444 using B31.3 i found the information below:
I cannot find coefficient with temp. is below 21 degree C (using B31.3 or All Code when open material database editor as the attched picture)
I google but not found the coefficient yet.
The coefficient to be enter in temperature field is clear for me.

update: the code 31.1 has values for negative temperatures.
