    Hot Rolled Strip Steel

    Tata Steel offers a choice of hot-rolled heat-treatable steels.

    Case-hardening and hardenable grades offer advantages across many applications. We exercise stringent control over chemical composition and production processes, resulting in a robust, consistent and reliable quality you can depend on.

    Heat-treatable steel

    Tata Steel offers a choice of hot-rolled heat-treatable steel. Its chemical composition and the production processes we employ ensure robust, consistent products. 

    Our case-hardening steel is suitable for wear-resistant components that must bear extreme fatigue stress. Our hardenable boron steels are can be processed to meet ultra high-strength requirements.

    Overview

     

    Case-hardening steel

    Case-hardening grades provide excellent formability and good punching quality. Our case-hardening steel is suitable for wear-resistant components that must withstand extreme fatigue stress.

     

    Hardenable steel

    Consistent formability combined with excellent strain hardening behaviour.

    The 22MbB5 and 26MnB5 grades are hot-rolled, uncoated products that are primarily used for precision tubes.
    In their ‘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 22MnB5 and 26MnB5 grades 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.
    These grades are also used in a number of end product applications in the automotive sector including stabiliser bars, drive and gear shafts.
