mechanical properties A217 C12a 1

[kiwi02]

Hello,
I´m working in an engineer office in germany and we are dealing with valve for power plants. Now the temperatuers of the fluids get always higher and there is needed material to achieve the requirements. Therefore there is the new material C12a for high temperatures. But we need the material properties according to the temperature to calculate the strenth for the valve body and so on. Where can I find such a table (strength versus temperature)? Who can confirm the correctness of the attached table from valve magazin?

This material has not yet been endorsed by ASME B&PV Code. It has been endorsed by ASME B31.1 (see 2007 Edition of ASME B31.1), and if you look in Appendix A there are allowable stress values as a function of service temperature for ASTM A 217 C12A.
