Influences of boron on the texture of low carbon deep drawing steel sheets produced by compact strip production

The influence of boron on the texture of low carbon deep drawing steel sheets was studied with B-contained and B-free low-carbon hot-rolled and batch-annealed strips produced by CSP(compact strip production) as experimental materials.Texture formation and development of the hot-rolled and batch-annealed strips were analyzed in terms of chemical composition and precipitates by electrolytic chemical phase analysis, internal friction and Raman analysis.The results show that the AlN content of B-free hot-rolled strips is much more than that of B-contained hot-rolled strips, but the latter texture is better than the former.The AlN contents of B-free and B-contained annealed strips are almost equal, however, the texture of B-contained annealed strips is bad.It is indicated that AlN is not only the determinant factor that affects texture development, but B and BN also have some influences.
