The purpose of this paper is to show the approach used by automotive and line pipe steel producers to develop a higher strength sheet steel with improved formability, toughness, and welding characteristics. Also covered are the appropriate stages of steelmaking and hot rolling leading to the development of a columbium-bearing steel with a minimum yield strength of 50 ksi. Typical mechanical properties and forming capabilities are presented, together with a discussion of the strengthening mechanisms and ductility factors utilized to achieve this formable 50 ksi product.
