A golf club head with an improved striking face is disclosed herein. More specifically, the present invention utilizes an innovative die quenching method that can alter the Young's modulus of the material of the striking face. The striking face portion of the present invention generally created from an α+β titanium alloy such as SP 700 that contains a β rich alloy composition to create more phase change in the alloying elements. In a preferred embodiment, the die quenching process could create a localized change in the material's Young's modulus throughout different regions of the striking face, resulting in a change in the Young's modulus of the material within the same striking face.
