Infrastructure
18 March 2026
Critical structures provides the strength, durability, and reliability needed
for demanding projects.
Indratek Steel Works, one of India's mid-tier integrated steel producers operating out of Raipur, was under increasing pressure to upgrade their TMT rebar output from the aging Fe-415 grade to the seismic-compliant Fe-500D and Fe-550D grades — a requirement driven by revised Bureau of Indian Standards specifications and growing demand from infrastructure developers under the Pradhan Mantri Awas Yojana and Smart Cities Mission.
The challenge wasn't simply metallurgical. Indratek's existing continuous-casting and rolling infrastructure was calibrated for lower-grade output. A full capital overhaul would have taken years and hundreds of crores. The alternative: a chemistry-first solution — introducing Ferovium's FV55 micro-alloying additive into the ladle metallurgy station to modify billet composition without restructuring the production line.
Ferovium's metallurgical team conducted a 6-week process audit at Indratek's Raipur facility before formulating a dosing protocol. The FV55 additive — a vanadium-niobium-nitrogen compound — was introduced at the ladle furnace stage, allowing precise control over the final carbon equivalency and ensuring the resulting rebar met both mechanical property targets and weldability requirements demanded by IS 1786:2008 standards.
