description

Graphitic steel rolls include carbide and spherolite within the pearlitic matrix of their structure. 

In working conditions where high reduction ratios exist, our graphitic steel quality meets the requirements of light and medium section mills because of its high resistance against breakage and wear. 

Rolls of this quality are also subjected to heat treatment after casting to provide the best microstructure and mechanical properties for rolling conditions.

  • Cr, Ni, Mo alloyed, steel based
  • Pearlite + Carbide + Spherolite
  • Constant hardness curve
  • Tensile strength: 500 – 650 N/mm2, Bending strength: 800 – 1000 N/mm2
  • On finishing stands for sections, universal rings
  • Resistance to wear
  • Resistance to thermal shocks
