Thanks for your interesting in HSS roll ring for bar mill sizing block
INTRODUCE：
Long term research and trial and error to finilize the process and chemicinal components. Compare to other supplier HSS roll ring, we supplied HSS roll ring segregation-free,no cracking, good resistance of impaction and hot hardness. Not only the high hardness but also the homogenous distribution of material from surface to core. The excellent abrasion resistance and super strength is the first choice of SBQ mill for sizing block. All the products inspect 100% before delivery.
