In the 1920s, titanium was used as a microalloying element. Initially, it was used in the trace-titanium microalloying treatment to improve the welding performance of steel. With the deepening of the research on the effect of titanium in steel and continuous progress of technology, such as smelting and rolling, the role of titanium steel is further highlighted and the product range is been continuously broadened. Representative products mainly include German QStE series of steel (titanium content ≤ 0.16%), YS-T50 produced by Youngstown Sheet and Tube Company, automobile beam steel NSH52T (titanium content: 0.08–0.09%) produced by Nippon Steel and so on. The research on the titanium microalloying technology and product development in China launched late and the first titanium microalloyed steel was not developed until the 1960s. The representative product was 15MnTi (yield strength: 390 MPa). Then, a series of products were gradually developed, such as the hull structure steel 14MnVTiRE (titanium content: 0.07–0.16%), automobile beam steel 06TiL, 08TiL and 10TiL (titanium content: 0.07–0.20%) and weathering steel 09CuPTi. After 2000, many researches were carried out on thin slab casting and direct rolling (TSCR) process, titanium microalloying technology and high-strength steel, and a great leap forward development was achieved in China. A series of 450–700 MPa grade titanium microalloyed high strength steel products was developed, which is mainly applied for the container, automobile, construction machinery and other industry fields. This chapter mainly introduces the representative achievements of titanium microalloyed high strength steel in China.
