Bainitic Nodular Cast Iron Rolls
Alloy elements of Ni. Mn. Cr. Mo etc. are added to bainitic nodular cast iron rolls for obtaining acicular (bainite-martensite) matrix in its microstructure of these rolls. Its strength and toughness is higher than Perlitic Nodular Cast Iron Rolls. Wearability is also better than the latter. These rolls can be produced by static casting or centrifugal casting.
