Description High speed steel rolls, produced by horizontal centrifal casting process, are all compound rolls with high speed steel as the work layer and nodular iron as the core. The material of HSS contains plenty of alloyed elements such as Mo, V, W, Cr etc. The high hardened eutectic carbides & second carbides, such as MC, M2C, M6C evenly distributed in tempered martensitic matrix, make the wear and thermal cracking reistance very excellent. Besides, the resistance to surface roughing is also good. In codition of hot rolling, the contact points between steel strip and the work rolls can form a thin adherent oxide film on the roll surface, which plays a good role in the wear features and the quality of the strip surface. HSS rolls are mnly used as the work rolls in the hot strip mills and the finishing stands of bar mills; rings of the universal section mills and finishing stands of the high speed bar mills.2.Chemical CompositionGradeCSiMnPSCrNiMoVWNbCent.HSS1.50-2.200.30-1.000.40-1.20≤0.03≤0.253.00-8.000.00-1.502.00-8.002.00-9.000.00-8.001.00-3.00CORE2.90-3.701.20-2.600.50-1.00≤0.15≤0.03≤0.08≤0.15≤0.053.Mechanical PropertiesTensileStrength(kg/mm²)500-800BendingStrength(kg/mm²)650-1000Elongation(%)0.2-0.64.
