Electro TMT CRS Gold Bars

Advantages

  • Longer life due to superior pitting corrosion resistance.
  • High yield strength coupled with good ductility and bendability.
  • No extra precaution required in material handling and transportation.
  • No maintenance during fabrication.
  • More suited to poor working conditions at site.
  • No extra precaution during welding.
  • Can be bent and rebent around very small mandrels.

Superior Properties

  • Helps in reducing corrosion from the time of construction.
  • Corrosion resistance elements like copper, phosphorous & chromium are added in the correct proportion to make steel corrosion resistance.
  • Quenching technology ensures high strength with ductility.
  • Distribution of corrosion resistance elements is homogenous from core to surface.
  • The high ductility ensures the steel can undergo permanent changes in shape without rupturing.

Suitable for Application in

  • Marine environment
  • Brackish ground water
  • Saline sub soil
  • High rainfall & high humidity
  • Seismic zones
