CASE HSS rolls possess good hardenability; the hardness hardly drops from barrel surface to inner working layer. Therefore, the rolls from outside to inside have similar good wear resistance.
Because spin-casting high speed steel outer shell can employ graphite steel or nodular iron as core material. Thus, journal has good strength, and core has little chance for breakage, In that case, improves bending strength of HSS rolls, which is good for rolling strips.

| CASE HSS Rolls |
Due to the chemical addition of Vanadium, chromium, tungsten, molybdenum, niobium and other alloy element, CASE HSS Roll has good thermal stability, high hardness under high-temperature, and excellent wear- resistance as hot work rolls.
When the HSS roll is working under good cooling conditions, barrel surface can from thin & compact oxidation film. This type of film will not be so easy to fall off, thus improves the wear ability of rolls. Compared to other ordinary CASE HSS rolls wear less in the beginning, which is good for its wear ability.
The hardness of ordinary rolls while temperature rises. On the other hands, CASE HSS Rolls have a hardness above 80 HSD when the temperature is 5500 C. Due to this, it has excellent roll- failure resistance.
CASE HSS Roll have big swelling factor, good thermal conductivity, However, Barrel will swell, in return reduce the grooves sizes, thus keeps stable shapes of grooves. Especially, while rolling bar or rebars. It has better control of input material negative allowances.
𝐂𝐀𝐒𝐄 not only supplies 𝐇𝐒𝐒 𝐑𝐨𝐥𝐥𝐬 but also assists the end users as to how optimum performance and efficiency can be derived from these rolls. 𝐂𝐀𝐒𝐄 HSS Rolls are specifically designed and manufactured for bar mills, structure mills and strip mills.
