The working layer of HSS rolls are made of alloy V, W, Nb and Mo, and shaped in Centrifugal Casting Machine, with spheroidal graphite cast iron in its core.

◆ ADVANTAGE

◇ HIGH HARDNESS

The hardness of roll working layer to reach as high as 80-85HSC with the control of element

composition and heat treatment.

◇ GOOD WEAR RESISTANCE AT HIGH TEMPERATURE

It ensures good wear resistance at high temperature and uniform wear in the roll passes, as the

important metal elements are uniformly distributed in the martensitic structure, such as V (Vanadium),

W (Tungsten), Nb (Niobium) and Mo (Molybdenum).

◇ IMPROVING OF SURFACE QUALITY OF ROLLED PIECE

◆ APPLICATION
◇ Work rolls of finishing stands for hot strip mills
◇ Work rolls of finishing stands for hot bar mills
◇ Pre-finishing stands for high-speed wire mills
