The carbide microstructure of the semi-HSS rolls is similar to the HSS rolls but less carbide, about 5- 10%. The reason is that the strong carbide element, such as Cr, Mo, W, V, etc. Form refined and higher hardness of MC,M2C alloy carbide on the work layer. They inlay martensite base with high heat stability. The dispersing carbide has good micro hardness with high temperature. On the tempering process, the temperature of secondary carbide separated from the base structure of alloy carbide is higher than traditional M3C (usually above 5009C). Some Cr, Mo alloy form carbide and most of them dissolve in the matrix. That improves the matrix hardenability and thermal stability. hss rolls
The rolls are mainly applied to roughing stands of 4-high hot strip mill, medium stands of 4-high wire-rod mill and bar mill.
