Tata Steel has developed a new product for automotive manufacturers in response to market requirements for stronger and lighter steels.
The DP1000HY-GI is a high-yield, ultra high-strength steel that combines strength and formability and allows manufacturers to make lighter components without altering their production facilities. The material is ideally suited for the crash-protection structure of a vehicle. Tata Steel is one of a very small number of steelmakers to be able to offer this product.
The strength of the new steel allows designers to reduce material consumption, offering the potential of an eight to 15% decrease in component weight depending on the steel grade being replaced. Its superior formability makes it suitable for creating relatively complex shapes, while its optimal energy absorption capability is ideal for making crash-relevant components. DP1000HY also fulfils the requirements of the German association of car manufacturers, the Verband der Automobilindustrie (VDA), ensuring it meets the stringent safety requirements demanded by vehicle manufacturers globally. DP1000HY steel incorporates carbon and manganese to increase its strength and hardenability. It is available in a range of dimensions, in thicknesses of up to 2mm and widths of up to 1,400mm. It is finished with a hot-dipped galvanised coating, offering good corrosion protection and making it a cost-effective body structure solution.
Production of DP1000HY started in July. Tata Steel will process orders for new and existing customers from its production facility at IJmuiden in the Netherlands.
