GBR TMT Fe 500D has a more refined chemistry and higher elongation values making it more ductile than the other grades.
- Sulphur & Phosphorus is maintained under 0.040%
- Elongation values are a minimum of 16%
- Yield Strength is minimum 500 N/mm2 and Tensile strength of 545 N/mm2
- Higher Ductility makes this grade ideal for use in projects located in higher seismic zones
