thermal coefficient of resistance of stainless steel

I assume that when using the thermal coef of electrical resistIVITY to calculate the thermal coefficient of electrical resistANCE, the coef of thermal expansion has to be taken into account.

For the thermal coef of resistIVITY, I get 0.104% /deg.C

For the thermal coef of resistANCE, I get 0.096% /deg.C

No, do not "correct" the TCR resistivity value for thermal expansion. The TCR data are reported assuming the material has freely expanded, and is (remains in) an unstrained condition during electrical measurements.
