A selectively heat treated side intrusion beam includes a beam body having a center portion heat treated and end portions not heat treated. The beam body is affixed to end brackets that couple the beam body to the automotive vehicle door. The method for forming a side intrusion beam includes the steps of moving beam stock through a heater; controlling the heater to cycle between an on-state and an off-state with respect to predetermined portions of the length of the beam; quenching the beam stock; and, cutting the beam stock at untreated portions to form the beam body.
