Tata Steel has developed a hot-rolled, fire-resistant E350 structural steel designed to help buildings and engineering structures retain their structural integrity for longer in the event of a fire. The steel has been certified by the Bureau of Indian Standards under IS 15103, the Indian standard for fire-resistant structural steel.
The steel can retain two-thirds of its room-temperature yield strength at 600°C for up to three hours, drawing strength from an advanced alloy design based on an optimised combination of microalloying elements and microstructural engineering. This enhanced strength retention under elevated temperatures is intended to allow sufficient time for safe evacuation during a fire.
Subodh Pandey, Vice President of Technology, R&D, New Material Business and Graphene at Tata Steel, said material innovation is critical to enhancing structural resilience as fire safety assumes greater importance in modern infrastructure design, describing the BIS-certified steel as designed to enhance structural safety while meeting the performance demands of modern construction.
The steel is suitable for a range of fire-resistant structural components, including structural hollow tubes and sections for pre-engineered buildings, positioning it as a solution for safer, more resilient infrastructure.
Tata Steel Group is among the top global steel companies, with an annual crude steel capacity of 36 million tonnes and a consolidated turnover of around $26 billion for the financial year ending March 2026. The company operates across five continents with an employee base of over 77,000 and has set a Net Zero target for 2045.
