Abstract

A suction roll shell having a plurality of through holes is made of a stainless ferrite-austenite steel having a micro-structure essentially consisting of 35-65% by volume of ferrite and 35-65% by volume of austenite. The steel has a composition containing, among other things, 0.005-0.07 C and 0.15-0.30 N, in % by weight.
