Different Grades of TMT Steel and their Application

Nov 30, 2018 / By System Admin / in 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 on it.

What do you mean 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.

Which are the grades of TMT Steel and what are its applications?

Fe-415, Fe-500, Fe-550, and Fe-600 are the different grades of TMT Steel.

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 bendability 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.

Are there any specific criteria that TMT Steel has to satisfy?

Yes, TMT Steel has to satisfy Indian Standards specifications which have been mentioned below.
