550D and 500D Steel TMT Bars – What are the Top Differences?
Looking for 550D TMT steel bars? You would love to go for such types of Thermo Mechanically treated steel bars that have become widespread in usage today. With excellent bendability and elongation features, these stand out due to strength and many other characteristics. Today, these are commonly used for making constructions or buildings that have to support heavy loads. Many people wonder how 550D TMT steel bars are different from 500 bars. Here are some of the top differences you must know about.
Higher earthquake resistance
550D TMT steel bars are better for areas that witness a higher level of seismic activity. Often used in earthquake-prone regions, these can sustain construction structures for a longer time when the earth shakes violently. With a soft inner core, a strong outer shield and the necessary strength, these can hold up better during an earthquake. This also means that in the case of critical structural elements like bridges and high-rise buildings, these can be a better fit.
Higher yield strength
Due to higher yield strength, these are able to withstand more amount of force for a longer time. Fe 550D TMT Grade Bars can withstand a minimum strength of 550 MPa, proving to be stronger than Fe 500 TMT Grade Bars that can withstand 500 MPa. For the uninitiated, the yield strength of a TMT bar happens to be the optimal stress that it can be subjected to before its permanent deformation and inability to come back to its real shape.
More ductility
More ductile in nature, these have higher impact resistance. The bars can withstand the impact of earthquakes and other natural disasters more easily. These are more suitable for all those construction projects that need more structural integrity, such as industrial complexes, bridges, and high-rise buildings. You can find these Thermo Mechanically treated bars being used in various standard construction applications.
More steel savings
When compared to Fe550 steel TMT bars, the steel consumption of Fe550D is lower due to minimum to mean weight ranges. There is 4 to 5% savings according to IS standard when compared to Fe 550. Make sure that you check with the manufacturer that you plan to source your supplies from, to be assured of the quality and certification of the bars that you need for your vital construction projects.
Elongation percentage
In comparison to the Fe 500 grade, the Fe550 grade TMT bar has a higher elongation percentage. When the carbon content is reduced, it is possible to weld the steel bars with more ease. When the impurity of sulfur and phosphorus is reduced, TMT steel bars can be made stronger and more ductile.
As you can see, Fe550 grade TMT bars are better than Fe500 grade bars in several ways. If you need stronger TMT bars with a higher elongation percentage, you can rely on these for your construction projects. However, it is essential for you to source TMT bars of these grades from a top steel manufacturer, to be assured of the quality of the supplies that you get.
