    Hot-rolled - Steel for forming

    Hot Rolled Strip Steel

    Hot-rolled steel for cold forming is used for bending and deep drawing.

    Tata Steel’s forming grades offer consistency for reliable processing and low carbon content for excellent welding performance. The optimised chemistry of Tata Steel grade DD14+ offers enhanced formability for complex components.

    • Ympress® for weight savings and component strength

      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.

    • Direct rolled steel: optimising your processing

      The Ymagine® range is available in five high-strength, low-alloy (HSLA) grades that are easy to process. H500, for example, offers excellent formability in strong, lightweight automotive components in gauges that are hard to produce in hot strip mills.

    • Heat-treatable steel

      Tata Steel offers a choice of hot-rolled heat-treatable steel. Its chemical composition and the production processes we employ ensure robust, consistent products. 

      Our case-hardening steel is suitable for wear-resistant components that must bear extreme fatigue stress. Our hardenable boron steels are can be processed to meet ultra high-strength requirements.

    Overview

     

    Hot-rolled steel for cold forming is used for bending and deep drawing.
    Tata Steel's forming grades offer consistency for reliable processing and low carbon content for excellent welding performance.

    The optimised chemistry of Tata Steel grade DD14+ offers enhanced formability for complex components.
    DD13WR is particularly suitable for use in wheel rims because of its low aluminium content and controlled Mn:Si ratio. The low carbon content gives DD13WR excellent welding performance.

    Applications

    Automotive components
    Domestic appliance components
    Furniture
    Switch gear panels
    Wheel rims
    Tubes and sections

     

    Relationship with standards

    Tata Steel offers hot-rolled steel for forming in grades that comply with
    EN 10111: 2008 and in a special Tata Steel grade as shown in the table below.
    All grades are available in qualities suitable for galvanising.

    As the EN standard applies only to steel ≤ 11mm thick, please consult us about the properties of steel in other thicknesses.
