FRIENDS TMT Bars (Thermo Mechanically Treated Bars)

What are Thermo-Mechanically Treated TMT bars?

TMT Bars, Thermo mechanically treated bars are high strength deformed steel bars used in reinforced cement concrete (RCC) work manufactured with the latest QST technology. TMT bars have superior properties such as superior strength, higher ductility, better weldability and bendability. Thermo mechanically treated (TMT) steel, can be described as a new-generation-high-strength steel having superior properties which meet the highest international quality standards.

What is thermo mechanically treatment process?

By adopting thermo mechanically treatment process higher strength of TMT bars is obtained. In this process, steel bars get intensive cooling immediately after rolling. When the temperature is suddenly reduced to make surface layer hard, the internal core is hot at the same time. Due to further cooling in atmosphere and heat from the core, the tempering takes place.

When the bars are taken out of the cooling system, the heat flows from the core to the outer surface, further tempering of the bars, which helps them attain a higher yield strength. The resulting heat-treated structure imparts superior strength and toughness to the bars. The microstructure of the core is a very fine-grained ferrite and pearlite. TMT bars are also known as 'Quenched and tempered rebars', because of the quenching and tempering processes involved in making the bars.

The production of quality TMT bar depends on three major factors - quality raw materials, a properly designed and automated mill, and a well-designed quenching and tempering technology.

This process is expected to improve properties such as yield strength, ductility and toughness of TMT bars. With above properties, TMT steel is highly economical and safe for use. TMT steel bars are more corrosion resistant than Tor steel. All rebars must be purchased based on the properties of yield strength, tensile strength and elongation values.

What are "Friends 500" bars?

Friends Steel has developed rebars, 'Friends 500', with High Yield Strength with High Elongation Value.

This Steel is superior to Fe415 because of the excellent strength-ductility combination it offers. Simultaneously it fully confirms to statutory requirements. "Friends 500" Bars have the potential to be used in New High Rises and give better protection against Earthquakes and savings in terms of Steel Consumption.

As a mark of our commitment to quality we have discontinued the production of Fe 415 grade bars in Dia 10, 12, 16, 20 & 25. Only "Friends 500" bars are manufactured in these sizes.

Features of "Friends 500" Bars

  • Better ductility and malleability
  • High yield strength and toughness
  • More bonding strength
  • Earthquake resistance
  • High thermal resistance/Fire Resistance
  • Economical and safe in use
  • Good Weld-ability & Formability /No loss in strength at welded joints/Ordinary electrodes used for welding the joints
  • Superior Bend Properties
  • Better Elongation
  • Excellent Corrosion Resistance
  • High Fatigue Resistance

Friends rebars also come in Grades Fe 500D etc that have uniform and concentrated hardened periphery and the softer core will have the desired tensile strengths coupled with high elongation as required in seismic zones. Friends 500 bars with hardened periphery of about 25 to 30 % of the cross sectional area of the bar are ideal for civil constructions (constructions of houses, offices, etc.)
