thermal expansion of nodular iron

[sta67]

Can someone tell me where to find data for the thermal expansion of nodular iron below zero. I have searched in every resource I can find and only find values above zero. Or if someone has the data I just need a couple points like +68 to -100 deg F and +68 to -300 deg F. And if possible for ferritic and pearlitic if they are available.

Suggest you contact either society below for this information

http://www.ductile.org/

or

http://www.afsinc.org/

You will need to contact AFS or DIS for more specific information. I did attempt to perform a Google Search unsuccessfully. If you are looking for Ductile Niresist,then some information is available from NiDI publications. I tried to see,if any comparisons were available with unalloyed D.I, but there was hardly any reference. I have contacted a few knowledgeable friends in the industry for help. In case they respond, I shall communicate the same.

I have provided one such reference for you from Iron Castings Handbook.Please let me know if it helps.

The data isn't out there because these alloys are not usable at low temp.
Their DBTT is barely below RT.

Thanks to all for the comments. The reason I needed the info was not to use the material at those low temperatures, but to get some data for calculating contraction expected on liners that are shrink fitted in cylinders. The DIS found me one book that had one data point at -300 deg F and I could then extrapolate that with the above RT data that I had to get an approximate curve. Thanks again. sta67
