A106B Steel Material Properties
(OP)
I am looing for some material properties on A106B steel tubing. I founnd a source that has the tensile strength, but I am specifically looking for bearing and shear. Thanks in advance.

UTS - 60 Ksi
YS (0.2% offset) - 35 Ksi
Estimated Value
Shear yield point (0.58*35 Ksi) = ~ 20 Ksi
Ultimate Shear strength (0.75*60 Ksi) = ~ 45 Ksi
Bearing stress is not as mechanical property, it is a calculated value based on projected area * strength
RE: A106B Steel Material Properties
Bearing stress = force/projected area

The holes will elongate under combined tensile and shear stresses. The shear strength will be reached first so this is what you should use for your design assumption.
set the allowable bearing strength = calculated shear yield point/1.5
Once you have determined the allowable shear strength you can now estimate the projected or bearing area of the lap joint to carry this force. This is done by calculating the total cross sectional area of the lap joint in the direction of applied force and subtract it from the projected area of the fastener holes (number of fastener holes x the projected area of each hole under load). The difference in cross sectional areas would be the net cross sectional area of the lap joint that carries the dynamic force. Dividing the dynamic force by the net cross sectional area of the lap joint would determine the bearing strength. This can be compared to your allowable bearing strength value.
I used this simplistic example here for illustrative purposes.
