Resumen: Stainless steels are widely used in the chemical processing and power generation industries. They are, however, increasingly being considered for structural applications in, for example, construction and transportation industries, where they offer the advantage, over conventional structural steels, that painting or other corrosion protection is not necessary. This is especially true for duplex stainless steel (ferrite and austenite), which offers the advantage of high strength and lower costs over the austenitic stainless steels. Many applications in the chemical, power generating and structural areas mean that welded components and structures experience fatigue loading. However, there are remarkably few published fatigue data for welded joints in stainless steels, especially duplex. Fatigue test results obtained from four fillet welded joints are presented and evaluated in comparison with available published data, for the same details in C-Mn steels and current design S-N curves. In the basis of this research, fatigue design curves for these types of joints in stainless steels are proposed.
