Fatigue properties of stainless sheet steels in air at room temperature

Abstract

The number of stainless sheet steel applications involving cyclic loading in non-corrosive and mild corrosive environments is increasing. In the present work, the fatigue properties of two austenitic (AISI 301 and AISI 304) and two duplex (Avesta 2205 and SAF 2304) stainless steels have been studied using fully reversed strain controlled testing of smooth specimens in air and at room temperature. Since prestraining is a common operation for increasing the proof stress of austenitic grades, these grades were also tested in the prestrained condition. The fatigue strength has been evaluated as a function of total strain amplitude, plastic strain amplitude, stress amplitude, and using the Neuber parameter.MST/3155
