5 Interesting Facts on the Steel & TMT Bar of India
Steel is crucial to the development of any modern economy and is considered the backbone of human civilization.
India’s economic growth is contingent upon the growth of the India’s steel ndustry. Consumption of steel is taken to be an indicator of economic development.
TMT bar is specially treated as a high-strength, deformed steel bar.
It is manufactured using the latest technology, which makes it superior in quality and strength when compared to ordinary steel bars.
Here are a few important facts on TMT bars:
1. The TMT bars obtain their strength from Thermo-Mechanical Treatment they undergo.
In this process, ordinary steel bars are first subject to intense cooling (through quenching process in the Tempcore cooling system) just after they have come out of the rolling mill.
The sudden quenching process reduces the temperature of the outer layer, thus, hardening the bar.
However, the core remains hot. After further atmospheric cooling, it tempers. This makes the TMT bar ductile and super tough and gives ithigh strength.
2. In ordinary bars, the excessive presence of carbon affects its weld ability.
However, this problem doesn’t exist in TMT bars.
The low carbon content in TMT bars improves their ductility.
Carbon content in TMT bars is usually restricted to 0.2% to give the bars superior weldability without affecting their quality and strength.
The joints of the TMT bars can be easily welded using ordinary electrodes.
3. TMT bars not only have better ductility and malleability, but also are earthquake, thermal and corrosion resistant.
These bars do not lose strength at their welded joints and are safe to use for any kind of construction work.
India is a developing country and the country’s economy is largely dependent on this sector.
A former report from IBEF stated that “India’s finished steel consumption grew at a CAGR of 5.69 per cent during FY08-FY18 to reach 90.68 MT.”
India’s steel industry is in a stage of constant growth. The TMT bars produced here are made using the recent technological advancements making them better than before.
