Abstract:Taking Q355NE+SUS304 dissimilar steel welded joint as the research object.the microstructure,3.5 wt%NaCl+0.5 wt%Na2SO4 PH=5 solution corrosion fatigue life and corrosion fracture characteristics were studied,and the corrosion fatigue performance and fracture process of Q355NE+SUS304 dissimilar steel welded joint were analyzed.The results showed that:the sample-level corrosion fatigue limit is around 170MPa,the corrosion fatigue crack originated in the thermal affected zone of Q355NE,gradually expanded and finally broke in the welded core zone of the joint.and component-level of dissimilar steel welded joint corrosion fatigue passed the test of two million times under ultimate load of 4 tons,without damage.
Keywords:Q355NE  SUS304 stainless steel  welded joint  corrosion fatigue
