Corrosion fatigue of weld-bonded austenitic stainless steels in 3.5% NaCl solution
Corrosion fatigue and fatigue properties of weld‐bonded and spot‐welded austenitic stainless steels EN 1.4301 and EN 1.4318 in 2B or 2F and 2H conditions were investigated. The corrosive environment was 3.5% NaCl solution at + 50 °C. In air the fatigue strengths of the weld‐bonded single spot lap‐jo...

Summary: | Corrosion fatigue and fatigue properties of weld‐bonded and spot‐welded austenitic stainless steels EN 1.4301 and EN 1.4318 in 2B or 2F and 2H conditions were investigated. The corrosive environment was 3.5% NaCl solution at + 50 °C. In air the fatigue strengths of the weld‐bonded single spot lap‐jointed specimens were significantly higher than those of the spot‐welded specimens used as reference. In the corrosive environment the difference was markedly reduced. The failure mode of the weld‐bonded specimens was adhesive in the corrosive environment and cohesive in air. The difference in the failure mode of the weld‐bonded joints did not affect the fatigue crack initiation in stainless steels, which always occurred at the outer edge of the corona bond area. |
