Product Description
High chrome cast iron roll

 Properties
Thanks to its high content of M7C3 type carbide in the range of 20-30% and discontinuous network distribution of carbide, the roll offers a high wear-resistance performance. The matrix consist of tempered martensitic and sorbite with finely-dispersed secondary carbides (M7C3, M23C6 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 rolling process.
