Hot-rolled DP600-UC Advanced high strength with excellent stretch formability characteristics DP600-UC is a hot-rolled, pickled and oiled advanced high-strength steel grade. The microstructure of dual phase steels consists of hard martensitic or bainitic phase interspersed in a soft ferritic matrix. This microstructure results in a steel grade featuring high strength combined with excellent drawability. DP600-UC also has a low yield ratio (Rp/Rm), resulting in a strong work hardening capacity, which means that the component increases in strength during the sheet stamping process. This makes DP600-UC especially suited for complex shaped components requiring high strength in final form. Typical applications of DP600-UC include relatively complex shaped wheels and chassis components which require high strength for crash or durability performance. Mechanical properties DP600-UC conforms to both the Euronorm HDT580X and the VDA 239 HR330Y580T-DP specifications.
