Prospects and State of the Art of TMCP Steel Plates for Structural and Linepipe Applications

Higher strength and higher thickness are ongoing demands on plates for pipes and structural applications. At the same time other properties like toughness and weldability must be kept or even be improved. As a consequence these demands must be achieved with limited addition of alloying. Specific aspects must be incorporated in the design of thick plates. To exploit the mechanisms of property achievement effectively and to compensate certain disadvantages of thick plate production appropriate mill equipment is necessary. Utilization of TMCP provide the basis to meet these goals.
