Abstract
Failure analysis of a paper machine duplex stainless steel suction roll material demonstrated that the mechanism of failure was intergranular stress-corrosion cracking followed by fatigue. Crack initiation was related to both the heat treatment of the alloy and the chloride content developed in the system during paper machine shutdowns. Crack propagation occurred during normal operating conditions by a corrosion fatigue mechanism.
