Titanium or stainless

[howie105]

A quick question about people's preferences for titanium or stainless steel and why. Looking at an adapter from Ddave that offers both options. Thanks

I am allergic to titanium so stainless for me.

i love SS because i can put it in a dishwasher. if it is real SS there came no rust.

i did it with the complete Dynavap + Hopper Frontends too with no problems

thats why i prefer SS always

All I know is that I much prefer Omni Ti DV tips over any and all SS tips cuz they heat up and cool more quickly and are much lighter... I also much prefer dabbing off SiC or boro/gems than any Ti or SS insert/cups.

Allergies aside, I think it comes down to use case. Titanium heats faster and cools faster. Stainless takes longer but holds the heat better.

With a single flame torch, I prefer a titanium Dynavap tip. Less wasted vapor with the quick heat up/cool down. With my IH, the titanium tip heats so fast, the load often gets scorched so it’s the SS tip all the way.

Sure I could have the heater tuned for Ti tips but it’s horses for courses as far as I’m concerned.

I want to thank everyone who have shared their observations and experiences.

For Dynavap tips I agree with what others have said to a t. I prefer a ti tip. The quicker heat up time lends itself to smaller, smoother hits in my experience.

For just a material in the vapor path I think both realistically perform pretty equally from a taste perspective. I guess I've never tried to back-to-back a SS M condenser with a ti condenser, but aside from whatever taste the two might impart from contact with your tongue or lips I wouldn't think they would affect the taste of the vapor unless dirty--both are non-reactive metals, no?

Titanium is much more resistant to corrosion than Stainless steel.
I don't see any particular need for corrosion resistance beyond that of SS in our application though.

FWIW Dynavap uses Grade 316 Stainless steel, better corrosion resistance than Grade 304 commonly used for cookware and most things from stainless steel.

However, titanium usually becomes dull and thus damaged in the dishwasher

I am allergic to titanium so stainless for me.

The Mayo Clinic conducted a decade of patch testing and found no positive reactions to titanium

My primary care doc and two dentists say its so not a self diagnosis.

I am allergic to some crazy stuff (latex, banana, melon to name a few) so I was curious.

Blood based testing may give an more accurate measurement of titanium reactions than patch testing. Titanium particles are too large to penetrate the skin and the relationship between skin sensitivity and systemic hypersensitivity is ill-defined. The Mayo Clinic conducted a decade of patch testing and found no positive reactions to titanium despite published cases of titanium hypersensitivity.

Ever inhale the fumes from an oxidized SS screen?

In recent times I started questioning all materials which change colors as this suggests molecular level reactionary oxidation.....

 

[Bologna]

^Exactly. Are all these Ti tests heating it red hot or are they talking about the polished joints and swiss cheese "golf clubs" used for hip replacements etc...? (that's what my buddy calls em, he's had both hips replaced twice already at 54 cuz of ileitis at 14 yo and the massive doses of Prednisone that destroyed his cartilage.)

So stainless depending on grade can cause nickel issues in people allergic to nickel which is a large % of the population apparently.

Wait a sec..........is this a dynavap thread?

Sorry @Planck You are definitely right.

I had aluminum in my head and I totally mixed it up. I take everything back

but somehow I always prefer stainless steel

Here's a couple of papers if anyone is interested.
The first is behind a paywall (fuckers) the abstract is available and states in part.

An extensive programme of cooking operations, using household recipes, has shown that, apart from aberrant values associated with new pans on first use, the contribution made by 19% Cr/9% Ni stainless steel cooking utensils to chromium and nickel in the diet is negligible.

This paper from the U.S. National Library of Medicine is available in it's entirety.
The sidebar has links to a number of papers on related topics

No worries mate. FWIW I don't have any titanium, it failed my cost benefit analyses. YMMV

Pans don't glow or oxidize like coils do.
I do some smithing and have some familiarity with metal fume and its related health concerns.
A lot of it is abstract and is more of a concern in a industrial setting.
I use kanthal coils in a couple 510 units and they definitely glow.......high aluminum content and definitely hot enough to be a perceived health concern I reckon time will tell for me there?

If it is the best stainless steel it should probably be the best then? I guess not all our created equally unfortunately and who knows with alloys, yeah I never wanted to torch screens clean because they turn black, does not seem good at all lol

I've also been told that titanium is extremely damaging to the environment, the whole process of extracting and producing it, and I'm not sure what benefits it really has aside from being lighter weight and faster to cool off than SS?? My minimal research!
