High chromium cast iron roll
Thanks to its high content of M7C3, type carbide in range of 20-30% and discontinuous network distribution of carbide, the roll offers a high wear resistance performance. The matrix is finely-disseminated secondary carbides (M7C3、M23C5 and M3C types), increasing therefore the wear resistance of roll, The Cr2O3 enriched oxide film on the roll surfaces is highly resistant to oxidization and plastic strain, making the roll extremely suitable for steel hot milling process.
