Fe 415 grade
A Fe 415 TMT steel bar is a highly ductile TMT reinforcement bar, which is manufactured for small-scale construction projects. It can be easily bent into the most complex shapes, making it perfect for small-load constructions.
Chemical composition (percentage max)
- Carbon – 0.30
- Sulphur – 0.06
- Phosphorous – 0.06
- S+P – 0.110
Mechanical properties
- Minimum Yield Strength – 415 N/sq.mm
- Ultimate Tensile Strength – 485N/sq.mm
- Elongation (percentage) – 14.5
- Ration (UTS/YS) – ≥ 1.10
Use in construction
Fe 415 is used for reinforcing residential homes, and small-scale infrastructures. They have high uniform elongation and are used in earthquake-prone regions. Construction firms may also opt for Fe 415 S or Fe 415 D if they require additional seismic stability.
Fe 500 grade
Fe 500 grade is regarded as a market-standard across many construction projects. Its alternatives, Fe 500 D and Fe 500 S, are popular choices that offer greater seismic stability.
Chemical composition (percentage max)
- Carbon – 0.30
- Sulphur- 0.055
- Phosphorous – 0.055
- S+P – 0.105
Mechanical properties
- Minimum Yield Strength – 500 N/sq.mm
- Ultimate Tensile Strength – 545N/sq.mm
- Elongation (percentage) – 12
- Ration (UTS/YS) – ≥ 1.08
Use in construction
Fe 500 bars are used across a range of residential, commercial and multi-storey projects. They offer greater tensile strength than Fe 415 to provide stability to high-rise projects, while resisting load better. Additionally, Fe 500 D bars offer greater ductility, making them perfect for infrastructure construction in areas with high seismic activity. They have a superior minimum percentage elongation of 16 percent, compared to that of Fe 500 at a standard 12 percent.
Fe 600 grade
Fe 600 grade bars have greater tensile strength and can be used across a range of large-scale projects.
Chemical composition (percent max)
- Carbon – 0.30
- Sulphur – 0.055
- Phosphorous – 0.050
- S+P – 0.100
Mechanical properties
- Minimum Yield Strength – 600 N/sq.mm
- Ultimate Tensile Strength – 585N/sq.mm
- Elongation (percentage) – 10
- Ration (UTS/YS)- ≥ 1.06
Use in construction
Procurement managers in construction can source Fe 600 grade TMT when developing industrial and large-format infrastructure projects. Bridges, industrial projects, and structures requiring high load-bearing capacities can leverage Fe 600 grade TMT. They’re especially impactful in coastal, marine and underground environments as well.
Fe 600 grade
Fe 600 is one of the strongest TMT grades that construction firms acquire while developing heavy-duty infrastructure projects, bridges, and marine facilities. They offer greater tensile strength, and ensure lesser steel congestion within the reinforcement.
Chemical composition (percentage max)
- Carbon – 0.30
- Sulphur- 0.04
- Phosphorous – 0.04
- S+P – 0.075
Mechanical properties
- Minimum Yield Strength – 600 N/sq.mm
- Ultimate Tensile Strength – 660N/sq.mm
- Elongation (percentage) – 10
- Ration (UTS/YS)- ≥ 1.06
Use in construction
Fe 600 may be used in the construction of expressways, steel plants, water towers, commercial properties, and industrial zones. They’re used extensively when large-scale projects need to be developed keeping load bearing, and durability.
