Duplex SS (UNS 31803) - Coefficients of Expansion
(OP)
I looking for Coefficients of Thermal Expansion for Duplex SS (UNS 31803) for temperatures less that 25 deg. C. down to -10 deg. C. or less.
If you can provide this info, please cite the source as well.

RE: Duplex SS (UNS 31803) - Coefficients of Expansion
Look in the Outokumpu duplex lit.
If your whole temperature range is only -10 to 25 then you are talking about some small amounts.
The number that I use is 11x10e-6/C for all duplex grades near room temp.

Start with the below mentioned link
http://www.smt.sandvik.com/heatexchangers
click TECHNICAL CENTER>>MATERIAL DATASHEET
Select the product form (plate, seamless pipe etc). For UNS 31803 you may select SAF 2205 (i.e. UNS 32205 which is pretty much equivalent) and generate the "dynamic datasheet".
Coefficient of thermal expansion generated within this datasheet.
