Textures of strip cast and hot rolled ferritic and austenitic stainless steel

Abstract

AbstractRecent progress in strip casting technology allows the production of ferritic and austenitic stainless steels with the same geometry and quality as those provided by conventional hot rolling. This enables the entire hot rolling procedure to be bypassed. The random initial crystallographic orientation distribution through the thickness of the cast strip leads to more homogeneous properties of the final steel sheet. The latter effect eliminates the well known ridging phenomenon in ferritic stainless steel which often deteriorates the surface quality of initially hot rolled bands. In the present paper the crystallographic texture of strip cast ferritic and austenitic stainless steel is examined in various through thickness depths. The results are compared with those for conventionally produced, i.e. continuously cast and subsequently hot rolled specimens.MST/3010
