Properties

Since 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 the wear resistance of roll. The Cr₂O₃ enriched oxide film on the roll surface is highly resistant to oxidization and plastic strain, making the roll extremely suitable for steel hot rolling process.
