At this year, demand for automotive steels with high strength increases including pipe applicationfor automotive. This is in-line with current trend of automotive steel demand which require shigher strength and thinner gage. Furthermore, automotive application requires an excellent surface quality and consistency of mechanical properties along the strips.This paper describes the development of 490 MPa plain carbon steel strips by optimizing rolling temperature in hot rolling instead of using HSLA steel as raw material. Customer requires Hot Rolled Pickled Oiled KS 49 requires with tensile strength 490 MPA minimum and elongation 18% minimum.
