The Rarest of ALL Mags ( I don't even have one)

[Pneumagger]

If you mail me your valves I'll weigh them for you.

If you get the valve back it's stainless steel, if you don't get it back it was titanium.

:rofl:

Im rolling too.

hmmm, this is an interesting story. makes me wonder if my classic is one.

[paintballfiend]

Just checked...nope, no Ti valve on my mag.

[FiXeL]

If regular valves are stainless then they should have some magnetic properties. Titanium won't.

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)

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?

How much for the spork?

[PumpMag]

another reason why Automags are here to stay

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 ?

(just kidding lol)

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.

Whoa! I think someone's been to school

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.

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" ?
