Enhanced High Chromium Cast Iron Roll (En-HiCr)
Enhanced high chromium cast iron roll is widely applied as work roll of the front stand of HSM. The constitutions are characterized by 20-30% of M7C3 carbides of great hardness evenly distributed in the matrix of tempered Martensite so that the durability and anti-thermal fatigue performance are great.
