Product Description

Nodular irons belong to a group of cast iron in which most of the carbon crystallizes as spherical particles known as graphite nodules. Wide range 
of properties may be obtained by adjusting the three major alloying elements: Cr, Ni and Mo.

The low nickel grade (FerriticIron) provides optimal hardness with high strength and toughness. The medium nickel grade (Pearlitic Iron) has higher surface hardness necessary for intermediate and finishing. High nickel and molybdenum grade (Bainitic/Acicular Iron) provide excellent mechanical properties at high working temperature in terms of strength, toughness, and hardness.

Nodular cast iron is the most common roll grade in hot rolling of billets, sections, bar and wire rod, narrow strip and seamless tube. Pearlitic iron rolls with additional Cr content can give better hardness penetration that is suitable for rolling sections with deep grooves.

Rolls from these grades can be produced by static or centrifugal casting.
