Abstract
This process for producing a steel sheet is a process for producing a high-strength steel sheet having a tensile strength of 780 MPa or higher, and includes a continuous annealing step in which a steel sheet having a given chemical composition is heated to a temperature in the range of 750-900ºC and the steel sheet is held in the temperature range for 0-300 seconds, thereby conducting continuous annealing. In the continuous annealing step, the atmosphere inside the furnace is regulated so as to have a hydrogen concentration less than 10 vol%, during the period when the heating to a temperature in the range is conducted and during the period when the holding in the temperature range is conducted. When the steel sheet has a temperature of 700ºC or lower, the furnace-body average value of log(PH2O/PH2) is greater than -3.01 but less than -0.07. When the steel sheet has a temperature higher than 700ºC but not higher than 800ºC, the furnace-body average value of log(PH2O/PH2) is greater than -1.36 but less than -0.07. When the steel sheet has a temperature exceeding 800ºC, the furnace-body average value of log(PH2O/PH2) is greater than -3.01 but not greater than -0.53, and the dew point is lower than -10ºC.
