Electrosteel Castings Limited Kolkata, West Bengal

Ductile Iron (also known as Spheroidal Graphite Iron or Nodular Cast Iron) was invented in 1949. Ductile Iron retains the corrosion resistance of Cast Iron but has more than double the tensile strength [Cast Iron- 180 MPa (min), Ductile Iron - 420 MPa (min)]. The essential difference between Ductile and Cast Iron lies in the shape of the graphite in the microstructure of the metal. In Cast Iron, the graphite is present in plate-like flakes, which makes Cast Iron brittle. But in Ductile Iron, the shape of the graphite becomes a spheroidal nodule, which offers better mechanical properties and makes Ductile Iron sturdy, structurally stronger and shock-proof.

Suitable Grades for General Engineering, Structural, Rerolling & High Tensile Applications.Electrosteel TMT bars are produced in Fe 500, Fe 500 D & Fe 500 D CRS variety in IS 17862008 grade. Carbon Levels & Carbon Equivalent levels are kept to a much lower level than the standards. Product produced with low levels of impurities of Sulphur & Phosphorus.
