What is Fe 500D grade steel?
Fe 500D grade steel is one of the TMT steel that is used for construction purposes. Here ‘Fe’ is the chemical symbol of Iron and 500 is the minimum yield stress (N/mm2) and D stands for the ductility of the Tmt rod.
What is the difference between Fe500 and Fe500D steel?
|Physical properties||Fe 500 Grade||Fe 500D Grade|
|0.2 % proof stress/ Yield stress N/m2||500||500D|
|Tensile strength||8 % more than the actual 0.2 percent proof stress or yield stress but not less than 545.0 N/m2||10 % more than the actual 0.2 percent proof stress or yield stress but not less than 565.0 N/m2|
Even though the YTS ratio remains the same for both, the elongation percentage varies i.e., higher the elongation % the better will be the ability of the TMT steel to perform in extreme conditions.
|Chemical Constituent||Fe 500||Fe 500D|
|Carbon constitute (%max)||0.30||0.25|
|Sulphur constitute (%max)||0.055||0.040|
|Sulphur + Phosphorous (% max)||0.105||0..075|
Reduction in carbon content improves the weld-ability property of the steel, while the reduced impure contents of phosphorous & sulphur make the TMT rods more tough and ductile.
