  • Metallic coated - Advanced high-strength steel (US Standard units)

    The consistent quality of our galvanized advanced high-strength steel grades delivers numerous end product benefits.

    Our precise control of steel microstructure also makes processing easy and repeatable.

    Metallic coated - advanced high-strength steel

    Our ultra-high strength steel grades for automotive applications, such as HyperForm®, are lightweight and offer design freedom for complex parts. Their high yield and ductility ensure shape accuracy and tolerancing, which enable maintained in-service performance for difficult-to-form parts.

    Overview

    Our products include both dual phase and complex phase steels. Dual phase steels combine high yield strength with good ductility, ensuring excellent fatigue properties and energy absorption. These steels provide potential for weight savings in structural parts. They also benefit from good forming and deep drawing capabilities. Our complex phase steel provides good bendability and edge ductility, making it particularly suitable for the cold forming of simple shaped components.

    This section is provided in metric units to align with automotive specification formats.

    Applications

    • Automotive A-, B- and C-pillars
    • Box girders for chassis
    • Crash boxes
    • Support components
