The grade of steel is same for both it is 500N/mm2, but FE500D is more ductile than the FE500.
This enables the fe500D to withstand the sudden load adsorption capacity, which is encountered during earthquakes, cyclones, Tsunamies etc providing higher safety.
This shall be mainly used in the high seismic prone zones.
Nothing to do with the concrete and cement mixture. About the cost I don't have much idea.
Fe500 and 500 D TMT bars are both types of reinforcement bars used in construction. Fe500 refers to the grade of steel, indicating its yield strength of 500 MPa. On the other hand, 500 D TMT bars are a specific type of Fe500 bar that undergo additional processes like quenching and self-tempering to enhance their strength and ductility.

What is the difference between tmt 500 and tmt 500 d bars?
TMT 500 and TMT 500D bars are both types of Thermo-Mechanically Treated (TMT) steel bars with high tensile strength, commonly used in construction projects. However, there are differences between the two in terms of their manufacturing process and properties: 1. Manufacturing Process: TMT 500: TMT 500 bars undergo a standard thermo-mechanical treatment process involving controlled heating and rapid quenching, followed by self-tempering to achieve the desired mechanical properties. This process imparts the bars with high tensile strength and ductility. TMT 500D: TMT 500D bars undergo an additional process known as Direct Quenching and Tempering (DQT), which involves a more controlled quenching process followed by subsequent tempering. This additional step enhances the ductility and weldability of the bars while maintaining their high tensile strength. 2. Properties: TMT 500: TMT 500 bars typically have a minimum yield strength of 500 megapascals (MPa) and offer excellent tensile strength and ductility. They are suitable for a wide range of construction applications, including residential buildings, bridges, and commercial structures. TMT 500D: TMT 500D bars also have a minimum yield strength of 500 MPa but exhibit improved ductility and weldability compared to TMT 500 bars due to the additional DQT process. This makes them particularly suitable for structures requiring higher levels of seismic resistance and for applications where welding is necessary, such as in pre-fabricated structures or reinforcement in concrete. 3. Applications: Both TMT 500 and TMT 500D bars find applications in various construction projects where high-strength reinforcement is required. However, TMT 500D bars are preferred in projects where enhanced ductility, weldability, and seismic performance are critical, such as in high-rise buildings, bridges in seismic zones, and industrial structures subject to dynamic loads. In summary, while both TMT 500 and TMT 500D bars offer high tensile strength, the additional DQT process in TMT 500D bars results in improved ductility and weldability, making them suitable for specific applications where these properties are essential. Builders and engineers should carefully consider the requirements of their construction projects and select the appropriate type of TMT bars based on structural design, environmental conditions, and performance criteria.
