Urgent: Mechanical Properties at High Temp for 9Cr Steel

Click For Summary
SUMMARY

The discussion focuses on the mechanical properties of welded 9Cr steel tubes, specifically the 9Cr-1Mo-V-Nb alloy, at high temperatures. The user seeks specific mechanical properties, including Poisson's ratio, yield strength, yield strain, ultimate tensile strength, and ultimate tensile strain at 650°C for both the P91 base metal and TGS-9Cb weld metal. The inquiry references a study by Yaguchi et al. (2010) and emphasizes the importance of these properties for advancing the user's research study.

PREREQUISITES
  • Understanding of high-temperature mechanical properties
  • Familiarity with 9Cr steel and its applications
  • Knowledge of welding processes and their effects on material properties
  • Experience with mechanical testing standards and methodologies
NEXT STEPS
  • Research the mechanical properties of P91 steel at elevated temperatures
  • Investigate the effects of welding parameters on TGS-9Cb weld metal properties
  • Learn about creep testing methods for high chromium steels
  • Explore the implications of multiaxial stress conditions on welded components
USEFUL FOR

This discussion is beneficial for materials scientists, mechanical engineers, and researchers focused on high-temperature applications of welded steel components, particularly those working with 9Cr steel alloys.

Urgent! 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

Poison’s 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.

What good would finding the properties of the weld metal do you its going to be changed as soon as you weld it- depending on an enormous number of factors- including dilution, current, weld cleanliness...
