Thermo-Mechanical Treatment (TMT), is a metallurgical process that integrates work hardening and heat-treatment into a single process.
Since TMT bars undergo thermo-mechanical treatment, they are extremely ductile and have high tensile strength. This makes it usable for every shape. It also provides great resistance to fire, earthquake, and corrosion. It is also easy to transport because of its lightweight build.
TMT bars are divided into various grades – Fe415, Fe500, Fe500D, Fe550 and Fe600. The number denotes the yield strength of the TMT bars and the letter ‘D’ denotes the ductility. Each grade has different properties and applications and therefore it is important to choose the right grade by knowing its application and usage.
TMT bar which contains a higher amount of Sulphur makes it prone to fire and a high amount of phosphorus causes fatigue to the bars.
Often due to the interaction of the rebar with moisture and air, the surface of the rebar develops a reddish colour which is being misunderstood as corrosion. Reddish rebar can be used for construction without any hesitation as long as they are in proper physical shape, weight and strength.
