S. G. Iron or ductile iron considered as one of the most versatile roll material now days. It is produced by small proposition of magnesium added to the melt as nickel-magnesium or altern-ative alloy, or pure magnesium in S.G Iron roll, the free carbon takes the shape of spheroids or nodules , thereby eliminating the notch effect to flake graphite and improving upon the mechanical properties of cast iron.   These Rolls are available in a wide range of hardness & composition for a variety of application. The matrix structure varies from Ferrito-Pearlitic, Pearlitic to Bainitic & Martensitic together with different carbide contents and graphite in the form of spheroids/nodules. Some critical grades are heat treated for higher strength. Chemical composition and structure are chosen to suit specific application. In many cases S G Rolls with an accicular matrix is preferred, because of its wear-resisting qualities. To this end, the iron is alloyed with nickel and molybdenum, to permit formation of an accicular structure in the as-cast condition. our quality of sgiron is also running in oval polish stands also. hardness will be given according to the customer requirements.

• Diameter: Upto 32 inches or 850 mm
• Length: Upto 80 inches or 2100 mm

Pearlitic spheroidal graphite rolls are concentrated characterized by nodular graphite as against flake graphite in the normal cast iron rolls. These rolls are excellent substitutes for many conventional steel and cast iron rolls due to a combination of superior strength. The softest grade has a pearlitic matrix containing ferrite around the graphite nodules, while the higher hardness grades have a complete pearlitic matrix. The carbide content increases pro--portionally with the hardness. accicular spheroidal graphite rolls also have a thick layer of chill. here the name of such rolls is based on the fact that the material consist of nodular graphite and carbides in under cooled austenitic pearlitic -bainitic matrix. the carbide content is considerably higher in the harder grades than the softer ones.
