Pearlitic Nodular Cast Iron Rolls

Pearlitic Nodular Cast Iron Rolls  Pearlitic nodular rolls are obtained by adding alloy elements of Ni, Cr, Mo into the nodular cast iron and following special heat treatment. Pearlitic nodular rolls have high strength, good thermal properties and resistance to emergencies as well as small hardness gradient of working layer. 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.
