Answer added by steel Market, Owner , Service 4 years ago. The HYSD bars have better bond with concrete due to corrugations or ribs on the surface of the bars. The steel bars can be cut, lifted and welded easily with commonly available tools and machines.
Better Bond: Concrete develops very good bond with steel. The Steel generally made of low Carbon and Silicon.
Two types of TOR steel bars are available. Nowadays these bars are replacing mild steel bars as reinforcement since their strength in tension and bond is higher. It should be free from loose mill scales, loose rust and coats of paints, oil mud or any other substances which may destroy or reduce bond. The latest development in steel bars is the production of CRS or corrosion resistant steel bars.

The TMT bars have following advantages: As the name implies it has comparively high strength than Mild Steel. It is used as window bars, for grills and for making steel gates.
However, steel has a few disadvantages which are listed below. Mild steel 2.
The cost HYSD bars is approximate same as mild steel but the use of HYSD bars leads to overall economy as the amount of steel required is less, due to its higher strength. If concrete is porous or if cover to the reinforcement is not sufficient, steel gets rusted and loses strength.
