Notes:
Fatigue strength of duplex stainless steel welded joints with longitudinal fillet weldedguess and with longitudinal flat side guess welded on plate was evaluated by hot spot stress, hotspot stress S-N curves were produced and compared with normal stress S-N curves. The resultsshow that the hot spot stress fatigue strength of the two kinds welded joints should be expressed byonly single S-N curve while nominal stress S-N curves can only be regressed respectively. The testdata are greatly above the S-N curves with slope m=3, recommended by IIW, which indicates thatthe slope m=3(IIW) has great safety factor in practical engineering application. But there is noappreciable difference in fatigue strength between duplex stainless steel and common structuralsteel with similar welded joints when fixed the test data to slope m=3
