TMT stands for “Thermo Mechanical Treatment”. It is manufactured by a quenching and tempering process which allows the outer surface to cool much faster than the inner core, making a temperature gradient from the bar axis to the fringe. This results in a harder martensitic outer surface while the inner core cools slowly resulting in the ductile inner core. This entire process increases TMT’s tensile strength, weldability, and stress resistance.
Mild steel is a malleable and highly versatile metal suited to a range of commercial, domestic and industrial usage. It benefits from the key qualities of steel including strength and formability, but thanks to its Read more…
