  • Hot-rolled - Structural steel

    Hot Rolled Strip Steel

    The guaranteed strength and good weldability of our hot-rolled structural steel help ensure ease of processing and reliable end-product performance.

    As with all our hot-rolled steel products, our structural steel is manufactured under tight controls – for consistent quality that you can depend on.

    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.

    Availability

    Structural steel products are available as follows:

    • As-rolled (+AR)
    • Normalised rolling (+N)
    • Suitable for cold forming (C)
    • Suitable for post-galvanising (Class 1)

    Relationship with standards

    Hot-rolled structural steel complies with European standard EN 10025: 2004 and is available in the grades shown in the table below.

    If normalised rolling (+N) or cold forming (C) is required, please specify when ordering. In these cases, this should be indicated by adding the relevant letter to the grade at the time of ordering (for example: S355J0C+AR). Cold forming cannot be guaranteed for structural steel that is not specified as cold-formable.

    The CE mark

    The CE mark is a symbol devised by the European Council to signify that a product meets the conditions of the applicable council directives. These conditions aim to ensure that the product is reliable and safe. Products that are “produced for incorporation in a permanent manner in construction works” fall under the Construction Products Directive. Hot-rolled steels covered by EN 10025: 2004 are used in such “works” and are therefore covered by the directive. For these products, Tata Steel’s test certificates bear the CE mark and Tata Steel has issued a certified Declaration of Performance (DoP). All the structural products produced by Tata Steel in Europe are CE-marked except for S185+AR.

    The maximum value for nitrogen does not apply if the chemical composition shows a minimum total aluminium content of 0.020% or if sufficient other nitrogen-binding elements are present.
    The nitrogen-binding elements shall be mentioned in the inspection document.
    For the chemical composition of cold-forming qualities, please consult us.
    The chemical composition of steels suitable for galvanising complies with EN 10025-2: 2004.
    All values are in weight%.

     

    Suitability for cold forming

    If chemistry suitable for cold forming (+C) is required, this must be specified when the material is ordered.

    Cold forming cannot be guaranteed for structural steel that is not specified as cold-formable.

     

    Suitability for galvanising

    If chemistry suitable for post-galvanising (Class 1) is required, this must be specified when the material is ordered.

    The maximum value for nitrogen does not apply if the chemical composition shows a minimum total aluminium content of 0.020% or if sufficient other nitrogen-binding elements are present.
    The nitrogen-binding elements shall be mentioned in the inspection document.
    For the chemical composition of cold-forming qualities, please consult us.
    The chemical composition of steels suitable for galvanising complies with EN 10025-2: 2004.
    All values are in weight%.

     

    Suitability for cold forming

    If chemistry suitable for cold forming (+C) is required, this must be specified when the material is ordered.

    Cold forming cannot be guaranteed for structural steel that is not specified as cold-formable.

     

    Suitability for galvanising

    If chemistry suitable for post-galvanising (Class 1) is required, this must be specified when the material is ordered.
