    Hot Rolled Strip Steel

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

    Case-hardening and high carbon 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 high-carbon grades supplied in the ‘as-rolled’ untreated condition can be processed to meet specific 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.

     

    High-carbon steel

    Hot-rolled high-carbon grades, supplied in the ‘as rolled’ untreated condition, are suitable for cold rolling to reduced thicknesses. They are often heat-treated to give the final mechanical properties required for the intended application. We offer five high-carbon grades to meet your processing needs.
