Thermo – Mechanical Treatment is a metallurgical process that integrates work hardening and heat – treatment into a single process.
Process:-
MS Billets are heated to approximate 1100c in a reheat Furnace. Then they are progressively rolled to reduce the billet to the final size and shape of reinforcing bar. After the last rolling stand, the billet moves through a quench Box. The quenching Converts the billet’s surface layer to marten site, and causes it to shrink. The Shrinkage pressurizes the core, helping to form the correct crystal structures. The core remains hot, and austenitic. A microprocessor controls the water flow to the queen box, to manage the temperature difference through the cross-section of the bars. The correct temperature difference assures that all processes occur, and bars have the necessary mechanical properties.
The Bar leaves the quench box with a temperature gradient through its cross section. As the bar cools, heat flows from the bars centre to its surface so that the bar’s heat and pressure correctly tempers an intermediate ring of marten site and bainite.
Finally, the slow cooling after quenching automatically tempers the austenitic core to ferrite and pearlite on the cooling bed.
These bars therefore exhibit a variation in microstructure in their cross section, having strong, tough, tempered marten site in the surface layer of the bar, an intermediate layer of marten site and bainite, and a refined, tough and ductile ferrite and pearlite core.

PURE STEEL
TMT STEEL REBAR
We supply physical and chemical passed tmt steel manufactured with advanced technology to produce Fe550 Grade with Low Sulphur and Phosphorus.
Advantages
EARTHQUAKE RESISTANCE
TMT rebars have a unique composition that makes them highly resistant to earthquakes. With a hard, external Martensite surface and a softer Ferrite-pearlite core, TMT is highly ductile and capable of absorbing seismic shocks
CORROSION RESISTANCE
The incorporation of Nickel, Chromium and Copper, TMT fights corrosion. The result is an Fe 550 TMT rebar that is long lasting, durable and dependable for weight-carrying structures.
FIRE RETARDATION
TMT rebars don’t lose their structural strength even in the face of intense heat up to 600 Celsius. This is possible through the particular quenching, cooling and shearing processes that the TMT bars are subjected to, during the manufacturing process.
SUPERIOR BENDABILITY & WELDABILITY
TMT rebars have enhanced ductile properties that allows for higher bending.
EXTRA CONCRETE BONDING
The unique and innovative ribs provide TMT rebars with excellent bonding ability with concrete
SAVING IN STEEL
TMT has extreme tensile strength, ductability and exhibits superior bonding with concrete. You will therefore require less steel rebars to achieve the desired strength during construction. This results in significant savingin costs.
