Did u use extensometer or not?
You have to construct 0.2% offset on the strain axis and get the 0.2% yield strength. Probably ur software would have that option!

Dear all,
Please refer to attached stress -strain graph obtained during tensile testing of SA 106 Gr B pipe.
While performing tensile testing of SA 106 pipes for Div 1 vessels ,we were not getting yield point even though required tensile strength is obtained.
The specimen were taken in both transverse and longitudinal direction from half thickness.
Kindly share your experience in finding the root cause..
Please inform if any further details is required for clarity.
