Product Description Graphite cast steel rollDescriptionThe graphitic steel rolls hae a metallographic structure consisting of carbides and a small amount of graphite in he pearlitic matrix. The rolls of this material has tensile strength and better resistance to thermal cracking than adamite rolls of the same hardness, and the wear resisitance of which is better than the cast steel rolls.Chemical Analysis GradesCSiMnPSNiCrMoGS1401.3~1.51.3/1.60.5/1.0≤0.035≤0.030.2/0.80.4/1.00.5/1.0GS1501.4/1.61.0/1.70.6/1.0≤0.035≤0.030.2/1.00.6/1.00.6/1.0GS1601.5/1.70.5/1.50.6/1.0≤0.035≤0.030.6/1.50.6/1.00.6/1.0GS1901.8/2.00.8/1.50.6/1.0≤0.035≤0.031.0/2.00.6/1.00.6/1.0Physical PropertiesDesignation of rollsBarrel hardness (HSD)Tensile strength (MPa)Elongation (%)Impact toughness (J/cm)GS14036~46>500≥1.0≥4GS15040~50>500≥1.0≥4GS16045~55>500≥0.5≥4GS19050~60, 55~65>500≥0.5≥4MicrostructureMicrostructure of working layer in the barrel: perlite + carbide/fine pearlite + small percentage bainite + carbideApplicationRoughing, intermediate stands of section mill and bar mill, roughing stands of high-speed wire-rod mill, roughing stands of hot strip mill, vertical rolls, back-up rolls sleeves, straightening rolls
