      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

      Poison’s ratio, ? = ?
      Yeild Strength, ?y (MPa) = ?
      Yeild Strain, ?y = ?
      Ultimate tensile strength, ?UTS (MPa) = ?
      Ultimate tensile Strain, ?UTS = ?


      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.

      Hi mri44

      I don't have any experience with both materials at high temperature. I think if you want to have accurate data. However, I can recommend to you some of the books that may contain such data.

      Creep and Fracture in High Temperature Components : Design and Life Assessment Issues
      http://www.comat.cz/files/proceedings/11/reports/1042.pdf

      you can also check the website: http://www.matweb.com to find the materials

      Good luck
