What's the point of having these? axisfoils.com/products/titanium-screw-set .. they caught my attention in a Real watersports Axis range presentation video. Looked it up on Axis page and find little description. Are these rust proof / resistant and require less / no tefgel maintenance?

They avoid (most of) the electrical corrosion issues, because their potential is closer than the other parts used. There are also stronger than stainless steel.

I have an adjustable carbon fin with mechanical parts made of titanium and other of stainless steel. In 6 months, the SS have rusted quite a lot, but the titanium stays pristine.

However, they are much harder, and thus prone to galling, and thus should always be used with some lubricant (tef gel, thread lockers, grease...) and never screwed too fast.

I think everyone misses the real point of titanium in SOME applications, like Armstrong.

Carbon fiber and stainless steel attack each other. The stainless will get light rust spotting from the reaction to the carbon. In this application titanium solves this issue. In aluminum applications, titanium does not perform better than stainless.

So for Armstrong, who imbends metal tapped plates inside carbon fiber parts, titanium is king. If they had used stainless, everyone would look in those tapped holes and see rusty stainless and cry foul.

Now understanding the true reason Armstrong needs to use titanium, why does Axis need it? Well they don't at all. Axis uses fiberglass, not carbon, where every stainless screw is mounted to avoid rusty screws. Yes, that zone in the middle of their wings where each hole is drilled, is skinned in fiberglass.

So why did Axis offer titanium. Marketing! So many Armie fanboys think titanium is some magically fantastic feature. Then even wrongly think thier screws are titanium. They are not. They come with stainless screws. The titanium is the tapped bits, not the screws.
