    Need Help!! Mechanical Properties at high temperature

    At first, My cordial respect to all members.

    I need help regarding my research study.
    I read a paper by Yaguchi, M., T. Ogata, and T. Sakai, Creep strength of high chromium steels welded parts under multiaxial stress conditions. International Journal of pressure Vessels and Piping, 2010. 87(6): p. 357-364.

    From this paper, i selected a specimen. Now i need some mechanical properties.
    Specimen: Welded 9 Cr steel Tube (9Cr-1Mo-V-Nb)
    Parent material: P91 steel
    Weld material: TGS-9Cb

    I need the Mechanical tensile properties (At 650 C) for both P91 (Base Metal) and TGS-9cb( Weld Metal).

    The properties are,

    At 650 C

    Poisonís ratio, ν = ?
    Yeild Strength, σy (MPa) = ?
    Yeild Strain, εy = ?
    Ultimate tensile strength, σUTS (MPa) = ?
    Ultimate tensile Strain, εUTS = ?


    Without these properties, i can not go ahead with my research study. I have no other way but to ask you for help.

    Any kinds of help would appreciated.

    May God Bless you all.

    Waiting for your valuable advice.

    Hello being a welder by trade I don't have the answer you need but I will give this over to our welding inspector who will probably know the answer. On another note this forum is for building flight simulators not piping code you might want to refer this question to a AWS or ASME inspector forum. Or one of many engineering forums.

    I see that you have posted this in quite a few other forums. On some of those forums you have received good answers so why post it here? I think this post should be deleted
