Abstract: The present disclosure relates to a method for manufacturing a high strength steel plate, comprising the step of providing a hot-rolled steel plate, the step of heating the steel plate to an austenitisation temperature range, the step of quenching the steel plate in two stages with a different cooling speed applied to each stage, the cooling speed of the first stage being higher than the cooling speed of the second stage, the first stage of the two-stage quenching step ending at a temperature range above Ms and the second stage of the quenching step starting at a temperature range above Ms and ending at a temperature range between Ms and Mf, the step of partitioning the steel plate. The disclosure also relates to a high strength steel plate manufactured with the method.
