Yes!… The steel contains high tensile strength, and that’s why it is prefered in concrete. However, not every steel provides the same yield strength. It differs based on its constituents.
Constituent | Fe 415 | Fe 415D | Fe 500 | Fe 500D | Fe 550 | Fe 550D | Fe 600 |
Carbon | 0.3 | 0.25 | 0.3 | 0.25 | 0.3 | 0.25 | 0.3 |
Sulphur | 0.06 | 0.045 | 0.055 | 0.04 | 0.055 | 0.04 | 0.04 |
Phosphorous | 0.06 | 0.045 | 0.055 | 0.04 | 0.05 | 0.04 | 0.04 |
Sulphur and Phosphorous | 0.11 | 0.085 | 0.105 | 0.075 | 0.1 | 0.075 | 0.075 |
The tension test is applied on a certain length of metal piece for each unit of steel batch to know its tensile strength. Apart from the tensile strength, the young’s modulus, ultimate tensile strength, will also be calculated.
Based on the tensile strength value, the steel will be graded. Difference between Fe415 & Fe500 Steel.
Fe denotes the symbol of iron (chemical element), and the number nearby represents the tensile stress of that steel. So if it is mentioned as Fe415, then we know that the iron has 415 N/Sq mm of tensile strength.
The tensile strength is one of the essential properties of steel. Apart from that, the other steel features, such as modulus of elasticity, yield strength, failure, or breaking point, also play a vital role in the strength of steel.
The tension test on steel ensures that the steel has every below-mentioned properties to withstand the structural loads.
The tension test on mild steel executed as per the IS code 1608.
Based on the steel specimen’s test result, its properties such as yield point, breaking point, and ultimate point data will be plotted as a graph.
Specimen | Dia of Steel bar in mm | Young’s Modulus in N/Sqmm | Yield stress N/Sqmm | Ultimate stress N/Sqmm | Nominal Breaking stress N/Sqmm | Actual breaking stress N/Sqmm | Elongation in % | Reduction of Area in % |
