Amravati TMT Bars are Thermo- Mechanically Treated for high yield strength. The process involves the rapid quenching of hot bars through a series of water jets, installed in a TMT Box, after they come out of the last Rolling Mill Stand. The bars are cooled allowing the core and surface temperatures to equalize. The bar core cools down slowly to turn in to a ferrite-rearlite aggregate. The strength of the bars is carefully controlled by optimizing the water pressure for their pearlitic core and the tough surface of tempered marten site, thereby providing an optimum combination of high strength, ductility and toughness. This product has wide use in concrete reinforcement structures, bridges, flyovers, dams, thermal & hydel power projects, industrial structures, high-rise buildings, underground platforms for railways, ports & road transport systems. TMT Bars at Amravati Steel give you the following features:
  1. Enhanced strength combined with high ductility
  2. No strength loss at welded joints
  3. Better high temperature thermal resistance
  4. Easy working at site owing to better ductility and bendability
  5. Savings in steel because against FE-415 available in market we give FE-450 steel.
  6. Thermal and earthquake resistance
  7. Good weldability
