I'm no metallurgist but I don't know if cryo-treating is what you want. As I understand it cryo-treating increases strength and hardness of the material. Harder material has a tendency to be more brittle. In a location that is going to constantly heat cycles, I'm not sure you want to have it be harder. I know we are very selective where we use high strength materials offshore.
I used to work with an engineer that knows a bunch about steel make up and thermal expansion. I'm going to try and get in touch with him and see if I can provide you with any additional information.
