If you want to spend a little time to Google the information, I can give you a hint. In ASME B&PV Code, Section II, Part D, Table TE-1 (Subpart 2), there are a list of COE for carbon and low alloy steels. ASME has grouped them, and the 1.25% Cr-1/2Mo falls in with carbon steel.

Typically CS COE ranges from 6.4 x 10^-6 in/in/deg F at 70 deg F(actual) to 9.5 x 10^-6 at 1300 deg F(actual). The mean COE from 70 deg F to 1300 deg F is 8.4 x 10^-6.
