Steel vs. Titanium for Outer Pipe Wall?
Hi,
Looking at options for pipes and I notice that some manufacturers use titanium and other stainless steel. What are the pros/cons?
Thanks!

Titanium will resist the penetration of armour piercing rounds from triple A.
Seriously, as the outer pipe is there to allow cooling air to pass between the pipes I don't think it makes any difference, some outer pipes are aluminium.

Most use .007-.008 SS for the inner pipe ( as well as outer pipe ) as it is light yet will withstand the odd wet start. I have seen and have had built outer pipes of titanium or even aluminum for that matter. The outer pipe does not see anywhere near the temps the inner does. Years ago we played with titanium for the inner pipe. The problem was on a serious wet start if the titanium started to burn through it would create a lot of sparks and actually spread quite quickly. SS is easier and cheaper to obtain.
That's been my experience anyway.

Titanium is lighter for the same dimensions of material, but as Dean said it can burn, typically when there's rubbing against other metals and it's damn expensive. Totally unnecessary for modeller use, and not generally used in full-sized applications where temperatures exceed 400 Deg C.

Titanium vs SS is my bread and butter.
For high temp applications, such as a tailpipe, SS or Inconel is the way to go. Typical comercial Titanium looses half of it's strength when exposed over 250F and it has high memory, meaning that everytime you cook it you loose 50% of it's remaining strength until it becomes unusable. Again, I'm talking about commercially available Ti. There are other very cool Ti toys that will behave totally different.
To me the most common sense is to use low cost Steel and replace after severe wear and tear. Its is cheap and serves it purpose. And they thicknesses we are talking about it is light as well.
