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, ...

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).

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?

Austenitic stainless steels such as types 304 and 316 are the most widely used, with roughly 18% chromium and 8% nickel content by weight. MSS are ferromagnetic alloys in which chromium and carbon ...
