A lot of folks seem frozen and refuse to do any searching at all. The above is where a large fraction of all of the successful fusioneers obtained their chamber spherical shell bodies.

6" 304 SS hemispheres will require 8" conflat rings with the standard 6" lipped inner diameter. These conflat rings are TIG welded to the hemispheres and the halves are then drilled and ports welded on as needed. The two halves are then bolted together using a copper sealing gasket to complete the sphere and the fusor chamber.

Note: This is not the only way to make a fusor as noted in many posting here. However, for those wanting this form of fusor, the above URL is a reliable source for good hemispheres.

Is stainless steel advantageous over other materials? I notice that supplier also has hemispheres of brass, aluminum and ...other non stainless steel. Is the choice of stainless just because its easier to weld, or is the added strength/corrosion resistance important?

All of this is answered many times in the forums. Stainless is the best material due to virtually any criterion you might choose. As noted, it need not be spherical.
