hmmm, this is an interesting story. makes me wonder if my classic is one.
Just checked...nope, no Ti valve on my mag.![]()
Automag valves were made from 304 stainless if i'm not mistaken, and that is austenitic stainless steel meaning its not magnetic. The only way to tell the difference is weighing it, compare color (i think this will be very hard even for an expierenced metal worker) or machine it (that tells alot about a material to a metalworker)Originally Posted by flyboy
I have acsess to a Brinell tester at the colege, will that do it? Will I have to scratch it? Will it really leave a mark on glass?

This is awesome!
Another reason why Automags hold their value and now some will be even worth more!![]()
Stupid question but will a magent stick to it?
Whats a magent ?Originally Posted by BigEvil

No, it's austentic (sp?) 300 series stainless steel.
The unit cell crystalline structure is different than that of normal steels. Normal ferrite (alpha phase iron) has a body cubic centered crystalline lattice, austenite (gamma phase iron) has a face centered cubic crystalline lattice.
Same metal, different properties - one of which is greatly reduced magnetic properties.

I am also a big fan of the light my fire sporks. Very good for a plastic spork.

Errr.. ok.. I've milled these kinds of stainless (316Ti is a real pain in the butt to mill) and never got any specific information about the stucture of the metal. 304 is kind of ok to do, but like all stainless steel you will have to be very specific about cutting speeds, or your tools will be gone in no time. The only thing we have on the shop floor is cutting data for that gives us cutting speeds and feeds for specific materials for the tools we use.Originally Posted by Pneumagger
Anyway, milling or turning stainless is not an easy task, and titanium is worse. (classified under super alloys)
I have a "smart mag" valve that is slightly lighter than my other valves. It was made to be light though, wasn't it? If not, is it possible that the Ti was made into some "smart valves" ?
wouldnt there be different conductivities of the metals?
probably would be easier to weigh but whatever
One way to tell is to spark it against a grinding wheel. Ti gives off distinctive white sparks, SS will look orangish.
Ok let the valve destruction begin...

I rubbed my spork against a few glass things and it left no mark, for whatever its worth
My smart mag valve has similar coloration. I have a fealing it has nothing to do with Ti but who knows.Originally Posted by back2integrity

I'm guessing the $1000 reward doesn't apply for a Ti valve with grinding or tooling marks on it huh ?
Titanium and 403 Stainless have different electrical resistivities, so you should be able to distinguish between them with an ohmmeter.

I don't believe it was posted and i'm sick of math. has anyone figured out how much a TI valve should way (please mention whether it's fully assembled, partially assembled, etc.)
This is hilarious! I can just picture everyone running to check out their old valve that has been laying around forever. Very comical.![]()
Well..........my valve is CF49520. I am not willing to spark it. How would I know if it was one of the valves?Originally Posted by AGD

find another one, compare the color VERY carefully, and weigh the two
