Cast irons with austenitic basic structure (Ni-resist)

  • Meaning high alloyed cast-irons for use on extreme conditions non-available for other sorts of material
  • all types of these cast-irons guarantee following specific atributes: corrosion resistance in aggressive enviroment, heat strenght, heat resistance, rubbing resistance, non-magnetism, sliding atributes,etc.
