    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.
