Abstract

See full text

A high-strength steel sheet and a method for manufacturing a high-strength steel sheet having excellent phosphatability and excellent corrosion resistance after electrodeposition coating has been performed, even in the case where the contents of Si and Mn are high. The method may comprise annealing a steal sheet by using a continuous annealing method, performing a heating process, controlling the maximum end-point temperature of a steel sheet in the annealing furnace, controlling the traveling time of the steel sheet, and controlling the dew point of the atmosphere.
