the exit of the rolled product,the ribbed bar is subjected to the TMT process,which
involves 3 stages.
Successive steps of rapid quenching in a special water system converting the surface
layer of ribbed bar into hardened structure.
2: The tempering process involving the flow of heat from the core of
the bar to the surface
Finally, the cooling the bars in atmospheric air on the cooling bed. This transforms
the outer case of the bar into tempered martensitic state, while internally the
bar will be a fine ferrite pearlite core. The TMT process eliminates all undesirable
qualities of the normally treated bar.
Pulkit TMT re-bar, therefore, attains higher strength and achieves excellent ductility,enhanced
bendability and superior weldability.
