what type of titanium is best for a wood stove/heater? 2

[mustard]

I am building a small ultralight woodstove/heater for a tent heater for backpacking9 personal usage! ).Using titanium sheet of .010 to .014 inch of thickness, what type/grade of Ti sheet should I be using? The Ti must be able to withstand repeated heating/cooling cycles with a max temp. of 1500 F., and not become brittle or crack.

why are you using titanium out of curiousity?

 

[phex]

Weight, I presume. As another example of the species "backpacker", I know of the hunt for grams to spare and titanium normally offers the best weight-to-durability ratio.

Sadly, I cannot contribute to the initial question - I'm just a chemical engineer without much knowledge in the area of MoCs.

Just my two cents,

Ti will oxidize at a high rate at Temp > 800F.

For cycling to these temps you really need to use a stainless or nickle alloy.
Some light gage 625 (Inconel) would be a great choice. It is stong, heat resistant and ductile.
Of course right now it is over $15/lb, but for a small about it shouldn't be a big deal.

Corrosion never sleeps, but it can be managed.

Here is something that might be of interest to you regarding a reliable, wood burning stove heater. No need to re-invent the wheel. By the way, you need to be very careful in trying to build your own heater. There are web sites that provide calculations for draft based on volume and configuration of the stove. Safety is most important!!!

My Dad and a friend built a woodstove for a 9x12 foot tent, made entirely of Inconel 625, approx. .06" sheet, TIG welded construction. The stove was a beaut. We would fire it red hot, and it would stand up to pretty severe abuse (pans dropped on it, wood chucked into it) without denting or warping. It has held up for >15 years, including being stored in the woods over winter, with no deterioration.
