The current construction of building structures is dominated by reinforced steel. Reinforced steel bars are preferred for their unmatched tensile strength which the concrete is weak to provide and ductility factor, that helps to withstand the load of the structure. There are different grades and different diameters (mm) of the reinforced bars in the current market namely Fe 415, Fe 500, Fe 550 and Fe 600.
TMT bars of the same grade usually have more than one type, while it is uncommon to hear about Fe 415D or Fe 415S. One must surely be heard of Fe 500 and Fe 500D, here Fe stands for iron, 500 stands for the tensile strength and D stands for ductility. Other than the names they also have a different chemical composition as well. When talking about carbon content Fe 415 has a maximum per cent 0.30 carbon while Fe 415 D and Fe415 S has a maximum carbon per cent of 0.25.
In this blog we will be taking a close look at Fe 415, the choice of the common man/ woman for building his/her dream home. We will taking a detailed look on how different grades of steel react to different standards tests undertaken by the Government of India. The number 415 in this grade of steel simply refers to its yield strength. Below some of the characteristics by different grades are marked.
