Mr. Chaboche,
I can confirm that the F65 material is videly used for flanges, hubs and other forged shapes. The ASTM standard gives you material values (see my thread http://www.eng-tips.com/viewthread.cfm?qid=257765&page=1 for moore data regarding strength).
The material is not listed, thus...
Metengr (& Stanweld),
Thank you for replying.
B31.3 is listing the X65 material with values up to 400ºF, which is more than enough for me. This material shows the tendency for allowable stress at increasing temperature.
Cheers
I'm looking for more info regaring ASTM A694 F65 at elevated temperature. This material is not, as far as I can see, listed in the ASME BVP code. I need to know how the yield & tensile properties change with temperature. Does anyone know?
(I suspect the ASTM standard not showing these values...
