  • Automotive - Hot-rolled

    Hot-rolled steel offers performance, versatility and value.  Our  hot-rolled strip steel range includes forming and high-strength, advanced and ultra high-strength steels.  All are specially designed for components commonly requiring higher thickness and durability within chassis and wheel systems.

    • 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.

    Steel with added benefits

    You can rely on the consistent quality of our hot-rolled steel. Our products comply with all relevant European standards. We have also enhanced many of our steel grades to deliver added benefits – both for end-products and customer processes. Our hot-rolled steel line includes exclusive Tata Steel products developed to increase your yield during component processing and lower your total cost of material application.

    The main benefits of our hot-rolled steel include:

    • enhanced in-service performance
    • extended product life
    • stronger, lighter products
    • opportunities to reduce your Total Cost of Ownership
    • repeatable, reduced-risk processing
    • opportunities to simplify processing steps
    • material yield improvements

    The tolerances for wide strip and slit wide strip comply with standard EN 10051: 2010.

    The specified values for wide strip do not apply to the uncropped ends of the coil (‘head’ and ‘tail’). The length of these uncropped ends is calculated using the following formula:

    length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.

    If required, this section of the coil can be removed. An additional cost may be charged for this.

     

    Edge camber

    The deviation from the edge over a length of 5000mm is:

    • with mill edges, no more than 20mm
    • with trimmed edges, no more than 15mm

     

    Flatness

    Requirements with regard to flatness can be agreed at the time of enquiry.

    Option for maximum crown values

    The table below shows the high crown C40 options available for hot-rolled products. Crown values on the C20-position, as well as minimum crown values on both C20 and C40 position, are also available on request.

    The tolerances for wide strip and slit wide strip comply with standard EN 10051: 2010.

    The specified values for wide strip do not apply to the uncropped ends of the coil (‘head’ and ‘tail’). The length of these uncropped ends is calculated using the following formula:

    length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.

    If required, this section of the coil can be removed. An additional cost may be charged for this.

     

    Edge camber

    The deviation from the edge over a length of 5000mm is:

    • with mill edges, no more than 20mm
    • with trimmed edges, no more than 15mm

     

    Flatness

    Requirements with regard to flatness can be agreed at the time of enquiry.

    Option for maximum crown values

    The table below shows the high crown C40 options available for hot-rolled products. Crown values on the C20-position, as well as minimum crown values on both C20 and C40 position, are also available on request.
