The superconducting properties of Tc, Bc2 and Jc were investigated in a residual strain state of pre-strain for bronze processed commercial multifilamentary Nb3Sn wires. It is found that the temperature dependence of Bc2 under strain obeys [1-(2/3) (πT/l.75Tc)2] near T = 0 and (l-T/Tc) near Tc. The establishment of the temperature scaling law of a global pinning force Fp = JcxB is confirmed in commercial Nb3Sn wires.
