  • Hot-rolled - Steel for linepipes

    Hot Rolled Strip Steel

    This hot-rolled steel is used for linepipes for gas, water and oil conveyance.

    Stringent control of mechanical properties means you can always rely on the performance of our steel for critical cold-expansion operations.

     

    HSLA for enhanced product strength

    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.
