Anshu http://www.efunda.com/ is a good place to start when searching for materials properties online. They didn't have the thermal expansion coefficient for your specific alloy, but they give a (wide) range of value for low-carbon steels: 11-16.6 ppm/K. This matches up well for the values that Perry's Chemical Engineers' Handbook lists.
