Abstract: Disclosed is a high frequency heat treatment method of hot-stamping-treated ultra-high strength parts, which comprises: a first step of heating the parts until the temperature of a heat treatment zone thereof becomes the AC3 transformation point or higher; a second step of maintaining the temperature until phase transformation of the heat treatment zone to austenite is completed; and a third step of cooling the heat treatment zone to transform the structure thereof to ferrite-pearlite. The present method improves the energy absorbing efficiency by increasing the parts' elongation ratio by locally forming a softening structure which absorbs energy.
