The Non-Destructive Testing (NDT) for the Ti & other super alloys is definately for aerospace applications. The >400mm ingots could be for large shafts like those used on the main rotor of helos &/or propeller shafts of ships.
Very Interesting radome.

Why does Nose tip looks optically Transparent.
315 mm dia at the intersection. That's the Rudram-1/NG-ARM missiles' radome. Here is another look at it:

Many ceramic radomes use a nose tip that is of a greater mechanical rigidity than the radome's ceramic material. In the case of the NG-ARM we know the material is crystallized silica ( likely alpha-quartz). Silica has excellent electrical properties for the radome application, but it has very poor mechanical strength. Without a re-inforcement the radome is susceptible to breakage at hypersonic flight regimes.

Therefore a metal or dense crystal tip is added with a metallic wire frame to add to the mechanical strength. The frame remains hidden inside the radome where as the nose tip is visible. Here is the Astra's radome, notice the tip.

Even Navy designs are not indigenous in that sense as almost 60% subsystem including engines and main radar, CIWS etc all are foreign designs.
Still they give us huge advantage to choose whatever best available in international markets and even our own subsystems if nothing suitable is available like CMS,Sonar and other sensor systems, torpedo and other ammunition etc.
It’s not perfect but not bad either.
