    Hot Rolled Strip Steel

    Tata Steel’s high-strength, low-alloy grades offer formability and strength for demanding applications.

    The range includes our Ympress® and Tenform® HSLA – with grades that exceed the Euronorm, resulting in stronger and lighter products with increased yield and simplified processing.

    • Hot-rolled HSS for formability and strength

      Our high-strength, low-alloy grades offer formability and strength for chassis frames, suspension control arms, wheel rims.

      The range includes Ympress® and Tenform® HSLA – with grades that exceed the Euronorm, resulting in stronger and lighter products with increased yield and simplified processing.

    • Advanced and ultra high-strength steels

      Tata Steel's hot-rolled advanced steel portfolio has been developed to provide solutions enabling weight reduction for demanding and complex-shaped automotive applications within chassis and wheel systems requiring high strength and durability.

    • Ympress® for cost-effective weight savings

      Ympress® is Tata Steel’s hot-rolled HSLA product. It is highly formable and delivers weight savings and increased component strength. The result is lighter, stronger, more consistent products.

      Ympress® adds value to automotive, lifting and excavating and shipbuilding applications, among others.
