Tulsyan Chrome HCRM Fe 500D TMT rebars are high corrosion resistant, thermo-mechanically treated reinforcement bars engineered to offer superior strength, ductility and long-term durability in RCC structures. The 40 mm bar size provides excellent bond with concrete and optimised steel consumption, making it suitable for critical structural elements in residential, commercial and infrastructure projects.Produced from specially designed chrome-enriched steel and processed through a controlled quenching and self-tempering route, these bars develop a tough tempered martensitic rim with a ductile ferrite–pearlite core. This microstructure, combined with low levels of harmful impurities, delivers enhanced resistance to rust, fatigue and seismic loading compared to conventional rebars.

Key Features

• Fe 500D grade providing high yield strength with superior elongation values
• Chrome-based corrosion resistant chemistry for extended service life in aggressive environments
• Thermo-mechanically treated (TMT) HCRM bars with tough outer rim and ductile core
• Precisely rolled 40 mm ribs ensuring strong mechanical interlock and better bond with concrete
• Low carbon and controlled alloying for good weldability and crack resistance
• Uniform sectional weight and length enabling accurate bar bending schedule and optimised steel usage

Applications

• Footings, columns, beams and slabs in multi-storey RCC buildings
• Coastal, marine and industrial structures exposed to corrosive atmosphere
• Bridges, flyovers and metro rail structures requiring high fatigue resistance
• Water retaining structures, tanks and treatment plants
• Critical infrastructure and premium residential projects targeting long design life
