Do a hand calculation on the creep strain assuming constant stress of some value. You will see that the result is reasonable given the inputs. Since the stress result is not shown let's assume the entire part is at 100 MPa. Then given the inputs creep strain = (100x60x60) x (3.2555E-31)*(100^6.2)*(exp(-36386/1373)) ~ 1E-24. Are you sure the curve fit of the creep test data gave 3.2555E-31 for the first constant in Nortons equation? That is a very small number indeed.
