Shell Suction Rolls


Material with a high chromium and nitrogen content, and frequently molybdenum. Due to this material composition, it offers good resistance to localized and uniform corrosion

The duplex microstructure contributes to the high crack resistance caused by stress corrosion. The high yield stress of duplex steel also implies in high fatigue resistance


We use tubes supplied by Outokumpu, a company located in Avesta, Sweden, and since 1973 we have already produced more than 2.500 hot rolled pipes used in the manufacturing of Suction Rolls in Duplex Stainless Steel


The Shell is drilled by the gun-drilling process, resulting in significant improvement on the surface finishing of the holes
