- 5. TMT bars Thermo mechanicalprocessing, is a metallurgical process that combines mechanical or plastic deformation process like compression or forging, rolling etc. with thermal processes like heat-treatment, water quenching, heating and cooling at various rates into a single process TMT steel bars are steel bars that are manufactured with unique metallurgical process known as “Thermo Mechanical Treatment”. These TMT bars are approved by the Bureau of Indian Standards for building and construction projects

- 7. Why TMT barsonly Steel rods in construction ensure the strength and longevity. It is important to choose TMT Bar Manufacturer that ensures the quality of TMT Bar. TMT Bars that are manufactured at Integrated Steel Plant (ISP) are best in quality because it is made of pure iron ore.
- 8. Properties of TMTbars Ductility Tensile strength Yield power Thermal Resistance Corrosion resistance Ductility in TMT Bar is more important because it determines how much it can bend as per the construction requirement. Therefore, Elongation is one of the most important factor before you choose to buy TMT Bar Tensile strength is resistance of steel to breaking under tension. Yield strength is define as, the stress a material can withstand without permanent deformation. TMT bars are thermal- resistant. Inferable from this property, we can say all TMT bars can endure fire perils. TMT Bars are casted with a thermo-mechanical treatment making them highly rust and corrosion resistant.

- 10. GRADES OF TMT BARS Thereare basically only 4 types of grades used in India • Fe-415 • Fe-500 • Fe-550 • Fe-600i
- 11. What do youmean by the grades of TMT steel? TMT bars are typically graded as Fe 415, Fe 500, Fe 550, Fe 600i etc where the numbers indicate the level of stress that must be applied to deform it. For example, Fe 550 starts to deform when a pressure of 550 Newton/mm2 is applied to it.

The grades of TMT Steel and what are its applications Fe - 415: Due to its higher uniform elongation, it can be used in RCC Constructions in corrosion and as well as earthquake-prone zone. Fe - 500: The high corrosion resistance, excellent bend ability and great resistance on dynamic loading of Fe - 500, it is used in RCC constructions in building, bridges and other concrete structures. Fe - 550: It has similar properties of Fe - 500, but differs in the yield and tensile strength. It is also used in RCC construction that is exposed to coastal, marine or underground environment. Fe - 600i: Since it provides better toughness and has more yield and tensile strength when compared to other TMT Steel grades, it is used for large RCC construction purposes.
