As follows
We use the highest marine grade stainless steel available, Grade 316L.
Er not true, what about duplex and super duplex grades, which are also stronger than 316L which is actually quite soft.
The only other steel alloys that will resist corrosion better, (Inconel, Hastalloy, Monel, etc.) are more expensive than the Titanium we offer.
Again not true, if someone is charging them more for Hastalloy than titanium then i suprised
While it is possible for 316L to corrode, with the absolute minimum amount of care, it will likely remain virtually corrosion free. If it does corrode, it will be limited to light discoloration on the surface, which is easily removed with a scotch brite pad. It wont pit, and flake off as rust the way lower grades of steel do.
Some truth at last.
Primary causes of increased corrrosion on 316L are Velocity and temperture, unless you are diving in water above 40DegC (100F), or the Dead Sea 316L is fine. We use Super duplex in highly salted water at 90DegC (200F), so why you need titanium other than pose value is beyond me.
And the velocity issue wont be a problem even with a scooter, unless your are being towed behind a very fast boat
