Bainitic Nodular Cast Iron Rolls (SGA)

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 toughnes are higher than Perlitic Nodular Cast Iron Rolls, wearability is also better than latter. These rolls can be produced by static casting and centrifugal casting.

To ensure the best performance of SGA rolls, we might suggest CCSGA for better strength and hardness.We will also help you do the roll pass design. Our goal is to minimize roll failures and breakages.We can offer you different barrel radius from 300mm-1500mm.
