Applications: front finishing stands of HSM and ESP
Manufacturing process: static casting
Description: These rolls are spun cast with a working layer which consists of uniformly distributed complex carbides of vanadium, tungsten, niobium and molybdenum in the martensitic matrix ensures the uniform hardness of the working layer. HSS rolls have high hardness and good wear resistance at high temperatures.
Manufacturing process: centrifugal casting

Applications: Medium and Heavy Sections Mills, roughing stands of HSM
Description: These rolls are special hyper-eutectoid steel rolls alloyed with nickel, chromium and molybdenum. The extra carbon and special alloys give extra wear resistance and strength.
These rolls are statically cast and undergo a special high temperature heat treatment process of double annealing followed by tempering cycles to give a microstructure consisting of a fine pearlitic matrix with spherodised / broken carbide.
Manufacturing process: static casting.
Barrel hardness: 40-55 HS
Chemical composition, %:

Application: Bar and Rod Mills, Medium and Heavy Section Mills, Seamless Tube Mills
Description: Nodular cast irons belong to a group of cast irons in which most of the carbon crystallises as spherical particles known as graphite nodules. A wide range of properties may be obtained by adjusting the three major alloying elements: Cr, Ni, and Mo. The low nickel grade (ferritic cast iron) provides optimal hardness with high strength and toughness. The medium nickel grade (pearlitic cast iron) has higher surface hardness necessary for intermediate and finishing stands. The high nickel and molybdenum grade (bainitic/acicular cast iron) provide excellent mechanical properties at a high working temperature in terms of strength, toughness and hardness.
Manufacturing process: static or centrifugal casting
