  • Hot-rolled - Advanced and ultra high-strength steel

    Tata Steel’s range of versatile and advanced and ultra high-strength steels has been developed primarily to meet the needs of the automotive industry – increasing strength or reducing weight to help achieve optimal performance parameters.

    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.

    Overview

     

    Use of our steels allows increased performance of finished components through using steel with an increased strength. Alternatively, we can help reduce the component weight using steel with a lower thickness without compromising performance. This can increase your output per tonne of steel. Our hot-rolled advanced high-strength steels include complex phase, ferrite-bainite and hot forming steel grades.

    Ferrite-bainite - HR FB590

    Hot-rolled FB590 is a ferrite-bainite advanced high-strength steel offering excellent ductility and formability. It is particularly suited to automotive chassis and suspension applications where a combination of superior strength and fatigue performance is required on relatively complex shaped parts. FB590 offers a high hole expansion coefficient and high tensile strength – ideal for components with a significant amount of edge stretching. The tensile strength levels deliver excellent fatigue resistance as an additional benefit.

    HR XPF800-UC

    HR XPF800-UC combinines high strength with good fatigue resistance, outperforming HSLA and multiphase products of equivalent strength levels, due to it outstanding hole expansion capacity (HEC), averaging 90%, and a far superior minimum elongation of 14%.

    Complex phase – HR CP800-UC

    HR CP800-UC is a complex phase advanced high-strength steel featuring a very fine-grained bainitic matrix microstructure combined with a small fraction of ferrite and martensite phases. This microstructure results in a strength of at least 760 MPa combined with an optimal balance between hole expansion capacity (HEC) and material elongation. The balance enables the design of relatively complex-shaped components requiring high strength and fatigue performance to be manufactured by cold stamping or roll forming.

    Hot forming steel - HR HQ1500

    Our die-quenched hot forming steel HQ1500 is a hot-rolled ultra high-strength steel. It enables an excellent degree of shape accuracy and mechanical performance. Its ultra high strength delivers significant benefits – especially when it comes to weight saving. By switching to HQ1500 from high-strength low-alloy or dual phase steels, designers can reduce the material gauge - creating stronger, lighter structures. We can supply our hot forming steel in either an ‘as rolled’ non-pickled condition or pickled and oiled.

    The ‘as rolled’ condition is suitable for forming both prior to or during heat and quenching treatments. The steel’s hardness properties after heat treatment make it highly suitable for applications requiring high wear-resistance.

    Hardenable steel - HR 26MnB5

    Consistent formability combined with excellent strain hardening behaviour.

    The 26MnB5 grade is a hot-rolled, uncoated product that is primarily used for precision tubes.
    In its ‘as-delivered’ condition the material is considered ‘soft’, enabling the forming of relatively complex shapes. The final strength of the end product is provided during a heat treatment process, where the addition of boron leads to the strain hardenability of this carbon-manganese-chromium alloy. The 26MnB5 grade also features homogeneous material properties that enable consistent and predictable performance of the final component. The material is very clean, meaning the levels of impurities are carefully controlled, which helps with consistency in formability and weldability.
    This grade is used in a number of end product applications in the automotive sector including stabiliser bars, drive and gear shafts.

    Use of our steels allows increased performance of finished components through using steel with an increased strength. Alternatively, we can help reduce the component weight using steel with a lower thickness without compromising performance. This can increase your output per tonne of steel. Our hot-rolled advanced high-strength steels include complex phase, ferrite-bainite and hot forming steel grades.

    Ferrite-bainite - HR FB590

    Hot-rolled FB590 is a ferrite-bainite advanced high-strength steel offering excellent ductility and formability. It is particularly suited to automotive chassis and suspension applications where a combination of superior strength and fatigue performance is required on relatively complex shaped parts. FB590 offers a high hole expansion coefficient and high tensile strength – ideal for components with a significant amount of edge stretching.

    HR CP800-UC is a complex phase advanced high-strength steel featuring a very fine-grained bainitic matrix microstructure combined with a small fraction of ferrite and martensite phases. This microstructure results in a strength of at least 760 MPa combined with an optimal balance between hole expansion capacity (HEC) and material elongation. The balance enables the design of relatively complex-shaped components requiring high strength and fatigue performance to be manufactured by cold stamping or roll forming.

    Hot forming steel - HR HQ1500

    Our die-quenched hot forming steel HQ1500 is a hot-rolled ultra high-strength steel. It enables an excellent degree of shape accuracy and mechanical performance. Its ultra high strength delivers significant benefits – especially when it comes to weight saving. By switching to HQ1500 from high-strength low-alloy or dual phase steels, designers can reduce the material gauge - creating stronger, lighter structures. We can supply our hot forming steel in either an ‘as rolled’ non-pickled condition or pickled and oiled.

    The ‘as rolled’ condition is suitable for forming both prior to or during heat and quenching treatments. The steel’s hardness properties after heat treatment make it highly suitable for applications requiring high wear-resistance.
