  • Hot-rolled - Steel for pressure vessels

    Hot Rolled Strip Steel

    Our structural steel for pressure vessels delivers excellent impact toughness and weldability.

    Special grades offer guaranteed strength levels at temperatures up to 400°C and steels compliant with EN 10207 and/or EN 10028 for the manufacture of simple pressure vessels.

     

    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.
