TMT BARS

Made with Technology.

Thermo Mechanically Treated (TMT) steel bars are known as the new generation steel owing to their high strengths obtained exclusively in this method of steelmaking. TMT steel is manufactured by heating raw material at 1200^0c initially, after which it is austenitized. Then, the bars undergo a process called quenching which allows rapid cooling and conversion into martensite, the high strength structure of steel.

During Thermo Mechanical Treatment, the steel bars are made to pass through a specially-designed water cooling system. The bars are cooled in water for a specific period of time such that the surface is colder than the inner core that remains hot. This makes the heat flow from the inner core to outer surface, causing tempering. This additional tempering of steel bars helps to impart a higher strength to the steel thus treated.

TMT ADVANTAGE

  • Withstands bending and rebending due to low carbon content and higher elongation.
  • Safe and economic due to bendability, weldability and excellent ductility.
  • Retention of strength against fire hazards due to tempered martensite outer layer.
  • Superior strength and anti-corrosive properties due to special TMT process.
  • Earthquake-resistant due to soft ferrite-pearlite core which bears dynamic and seismic loading.
  • Fine welding features that allow butt welding and lap welding.
  • Superior bonding strength between bar and concrete due to external ribs.
