Bainitic Nodular Cast Iron Rolls
Bainitic Nodular Cast Iron Rolls are called SGA rolls which obtained by adding more alloy elements of Ni, Cr, Mo into the nodular cast iron and following special heat treatment, the matrix is bainite. SGA rolls have high strength, good thermal properties and resistance to emergencies as well as small hardness gradient of working layer. it is widely used in the intermidate stand of wire & Bar mill.
As Per your request to rolling mill rolls hardness, we will suggest you the most suitable rolls material, to ensure the right rolling mill rolls grinding amount or removal stock.
