DEVELOPMENT OF HOT-ROLLED 06TiL STEEL SHEETS FOR AUTOMOTIVE

Zhang Kui (Iron & Steel Research Institute, Anshan Iron & Steel Co.)  
In this paper a description of the production technology and the properties of hot-rolled lowC low-Mn Ti-containing steel sheets used for automotive members is presented. The addition of titanium in the steel has the effects on grain refinement and precipitation strengthening resulting in an increase of ductility and strength on the one hand. and on improvement of cold bending property because of modifying the sulfide morphology and lowering the pearlite content on the other hand. It was found that 100% was O.K in the wide cold bend test with d=0. As titanium is a strong carbide forming element, so the strength of the steel containing it depends greatly on the presence of dispersed TiC or Ti(C,N) particles. The actual stamping of automotive parts with 06TiL steel sheets showed that the reject rate was below 0.5%. This steel is of excellent cold formabitity and therefore suitable for the automotive parts undergoing heavy bending and stretching deformation condition, such as cross members and supporting frames.
