Enhanced High Chromium Cast Iron Roll (En-HiCr)Enhanced high chromium cast iron roll is widely applied as work roll of the front stand of HSM. The constitutions are characterized by 20-30% of M7C3 carbides of great hardness evenly distributed in the matrix of tempered Martensite so that the durability and anti-thermal fatigue performance are great.Table.1 Chemical CompositionSymbolCSiMnCrNiMoVEn-HiCr2.6-3.20.40-1.200.3.-1.2016.0-22.01.0-2.01.0-3.0<1.51.5400<33<<1010< Website:http://www.kdroll.com
