5 Must-know Facts about Thermo Mechanical Treated Steel

One of the simultaneous applications to steel is Thermo-mechanical treatment. This treatment involves heating and cooling. The mechanical treatment develops superior properties in steel by refining the microstructure. A large quantity of steel can be handled in vast amounts because of continuous automation control. With the TMT process, about 50 tonnes of steel can be processed. The temperature for sequencing in the rolling mill is set between 1200 – 1300°C. The thermo-mechanical treatment makes the steel have high ductility and strength. Know the crucial points about Thermo Mechanical Treated steel in this article. 

Interesting Facts About TMT Bars

Mechanically treated steel bars are the most vital material for building construction. The TMT bars help in constructing earthquake-resistant structures. The chances of damage during the seismic activities are meager if your building has TMT bars. Some of the interesting facts about steel bars are:

• The treated steel bars undergo Thermo-Mechanical Treatment. As per the name, the treatment gives the bars superior quality and ultra-strength. It is challenging to find any steel bars with the same strength and quality as TMT bars. 
• In the case of an ordinary steel bar, carbon is present in an excessive amount. Due to the surplus amount of carbon, the weldability of the bars is affected. But this issue is not the same in the case of TMT bars. Thermo-Mechanical Treatment makes the carbon content in the bar shallow. The treatment also helps in improving the ductility of the steel bars. The carbon content in TMT bars has a restriction of 0.2%. The restriction quantity gives superior weldability; at the same time, it does not affect the strength and quality of the bars. Ordinary electrodes can easily weld the joints of the steel bars. 
• Thermo-mechanical treatment helps the bars to be earthquake resistant. Most people invest their hard-earned money in building a dream house. Hence, building a home with suitable materials from the beginning can help you a lot. TMT bars are a vital construction material that is earthquake resistant, making your building stand straight even during an earthquake. Elongation and ductility help the steel bars maintain structural integrity by absorbing the shock without breaking during an earthquake. 
• The heat treatment also makes the bars corrosion-resistant. During the treatment method, the steel rods are not bent or twisted. This makes the steel bars devoid of residual stress, thus making the TMT bars corrosion-resistant. Even if the steel bars are exposed to water for an extended time, you will not find rust forming on the surface of the TMT bars. But in the case of standard steel bars, the common issue you might encounter is corrosion. Thus using normal TMT bars hampers the building’s structural safety in a short time. 
• Heat treatment makes the TMT bars increase their fatigue strength. The outer layers of the steel bars are imbibed with reliable power allowing the bars to construct a building withstanding any dynamic loading and other fatigue-related factors. 

The Bottom Line

It is essential to choose Thermo-mechanical Treated steel for construction purposes. The advantages and security you will get from steel bars are difficult to get from ordinary bars.
