In my practice, 304 Ss casting can indeed be welded successfully, but it requires careful attention to welding methods and post-weld treatments to avoid issues like sensitization. Sensitization occurs when chromium carbides form along the grain boundaries during welding, depleting the steel of chromium and reducing its corrosion resistance. This can be mitigated by using low er carbon versions of 304 Ss or employing methods like solution annealing. But overall, it's crucial to follow greatest practices to make certain the integrity of welded joints.
