ABSTRACT:
A method for producing two-phase steel sheets having a material quality equal to or better than the conventional two-phase steel sheets by an addition of a very small amount of B so as to considerably reduce the contents of steel constituents, such as Mn and Si, thus eliminating the problems concerning the production cost, descaling in the processing and material quality in the ultimate applications.
