| Synopsis : In the process of developing steel sheets for automobiles, Kawasaki Steel has been aiming at better formability of high strength steel sheets and the improvement of other various properties. Typical examples of the development includes, a new bake hardenable steel (BHT steel) sheet having characteristics in that not only yield strength but also tensile strength are increased by baking after coating, and Super HSLA steel sheet having excellent elongation and hole expansion property, both at a high level of performance through the refining of crystal grains brought about by dynamic recrystallization. Both steel sheets have been secured as the results of the sophisticated control of steel structure, performed at the application of completely new metallurgical findings, combined, as their basis, with new technology devised at the No. 3 hot strip mill in Chiba Works which initiated its operation in 1995. |
