These solutions aim at resisting risk of breakage in certain applications.

Name: Duocast®.


  • Cement.
  • Power Stations.

Equipment: Vertical Roller Mills – one-piece rollers + tables in some applications.

Tech specs:

  • Technology consisting of very hard and special cast iron inserts embedded in a ductile iron base.
  • The ductile iron core has a hardness of about 300 BHN and an elongation of about 7%.
  • HiCr iron inserts are held in the ductile iron by dovetails to form a mechanical bond when the base metal is cast.

Key Benefits:

  • Combines the hard wear resistance of the special inserts with the ability of the ductile iron to operate under very high mechanical stresses.
