This presentation discusses TMT bars and their grades. TMT bars are steel bars manufactured through a thermo-mechanical treatment process that combines mechanical and thermal processes. There are four main grades of TMT bars used in India - Fe-415, Fe-500, Fe-550, and Fe-600i - which indicate the level of stress required to deform the bars. Each grade has different properties making it suitable for different construction applications, such as Fe-415 being used in earthquake-prone areas and Fe-600i for large constructions. The presentation explains the properties, applications, and manufacturing criteria of the different TMT bar grades.

Here’s what, I’ll be presenting
1. What is TMT
2. Why only TMT
3. Grades of TMT
4. What do you mean by the grades of TMT steel.
5. The grades of TMT Steel and what are its
applications
6. Specific criteria that TMT Steel has to satisfy

4. What is TMT ?

5. TMT bars
Thermo mechanical processing, 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

6. Why only TMT ?

7. Why TMT bars only
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 TMT bars
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.

9. GRADES OF
TMT STEEL
BARS

10. GRADES OF TMT
BARS
There are basically only
4 types of grades used
in India
• Fe-415
• Fe-500
• Fe-550
• Fe-600i

11. 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.

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.
