Steel Rod TMT FE 500 & FE 500D

These steel bars are crafted under strictly regulated manufacturing process which makes them easily bendable. There is an important connection between concrete and steel. Concrete has great compressive power but relatively low tensile strength and ductility, therefore when it fuses with TMT steel bars; it gives rise to a highly ductile and tensile combination.

While both Fe500 and Fe500D TMT bars are good for different types of construction projects, the Fe500D TMT bars certainly comes with a greater ductile strength than the Fe500 TMT bars. The Tensile strength of steel remains the same for both these products. However, it is the overall ductility that makes all the difference. Ductility is the ability of the material, to plastically deform and adapt while being stressed with a tensile load.When a piece of ductile material is pulled, before rupture (breaking apart), is will deform, change its shape to adapt to the stress. By doing so it will also absorb energy, represented by the area under the curve AB’ in the picture below.

The opposite of ductility is brittleness. A brittle material absorbs, during stress, very little energy (the area under the curve AB) and is, usually, not even plastic (in the example below it has a very limited plasticity).
