Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for further improving a fatigue strength and a high tension steel plate formed product using this method by controlling a burr shape developed on a cut surface when the fatigue strength on the cur surface of the metal plate is improved by shot peening.  <P>SOLUTION: In a process for producing a metal plate formed product having a cut surface created by a punching work etc., the shot peening treatment is applied on the cut surface. The injection angle is set in a range of 20° to 45° relative to the direction perpendicular to the cut surface, and other treating conditions, such as injection speed, are controlled. Concerning the burr developed on the cut surface, the ratio the burr height Δt in the plate thickness direction from the metal plate surface to the burr width Δw in the longitudinal direction of the metal plate, Δt/Δw, is made to be ≤0.25. Since the fatigue strength of the cut surface of the metal plate is made greater than that of the base material by ≥ 10% in this way, the development of the fatigue crack from the cut surface in the mechanical structural parts used for automobiles etc., can be suppressed, and the service life and the safety of the parts are improved.  <P>COPYRIGHT: (C)2004,JPO
