But what some folks may not realize is that a joint between two austenitic stainless steels could also be considered a dissimilar-metal weld (Figure 3). 3. When is similar, not the same?

The weld is now hard and brittle, undesirable properties for a mechanical joint. In order to avoid this situation, the cooling rate should be reduced or the weld should be heat treated (tempered).

Ferritic/martensitic steels and austenitic steels are the primary candidate materials for advanced nuclear energy ... to further study the microstructure of the 316L and T91 oxide films, ...
