maximum ultimate tensile strenght for A106 gr B
(OP)
Hi,
I was tensile testing welded sample of A 106 gr B, and the guage is reading an ultimate tensile streght of 87 to 90 ksi, in the spec, the minimum yield is 35 and the minimum tensile is 60 ksi, is the 87 ot 90 too high, is there a guide as to what the max should be or a range. The electrodes are E6010 root and hot pass and and 7010 cap for a 2" A106 B stick welding.
Thank you.

Check your testing procedure and data.

but I know how to tensile test, the gage reads the pressure or the load which you convert UTS by converting to ultimate load and then to UTS by deviding by the speciment area.
I was just wondering if the value makes sense, it seems too high for me which makes me think the gage is faulty.

I'm also assuming that the failure occured in the base metal? Did you get elongation values? Typical for grade B is 24%-30%, depending on specimen area

In any case, the results you got appear to be reasonable as compared to the MTR's. The fact that the failure occured in the base metal and not the weld implies that the welding procedure [and welders] are good as well.
Looks like you may have gotten a material with mechanical properties similar to 516-70 for the price of Grade B.
