摘要（英）：

The invention discloses a life extension method of a hot stamping forming mold for a high-strength steel plate. The method comprises the steps of vacuum heat treatment, mold pretreatment, ion nitriding and maintenance. The invention further discloses an application of the life extension method to automobile production. Picking resistance, temper softening resistance and fatigue resistance of the hot stamping forming mold for the high-strength steel plate of an automobile are improved effectively, so that the service life of the hot stamping forming mold for the high-strength steel plate of theautomobile is prolonged 2-3 times, the use requirements of the automobile production industry for long service life and high wear resistance of the hot stamping forming mold for the high-strength steel plate are met, mold cost of a mold user is reduced greatly, and the method has extensive market application prospect.
