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.
In IS 1786-2008 Clause no.4.2 , Chemical Composition and Table 3, Mechanical Properties of High Strength Deformed Bars and Wires the difference between TMT 500 and 500 d is clearly mentioned.
tanisp is far beter than pullkit,, pulkit is just an ordinary steel ,,
HCRM is HIGH CORROSION RESISTANT MARINE GRADE STEEL - BB GOYAL
meaning of 500 D in TMT bar
