    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® 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.

    Overview


    Our high-strength steel grades have been developed to meet a wide variety of applications. The consistent quality of these steels means they can be relied on to deliver benefits for your end-products and processes.

    The high yield strength of Ympress delivers weight savings and increased component strength. This can help you create lighter, stronger products and increase yield through down-gauging. Consistent properties and tight control of material thickness allow trouble-free, repeatable processing. Ympress can be easily welded and galvanised. Its high surface quality can lead to fewer processing steps.

    Applications

    • Wheel rims
    • Chassis and suspension components and assemblies
