Does anyone know what temperature titanium turns blue?

Just a question of curiosity as my exhaust tip is turning slightly reddish with a hint of blue.

 

what exhaust is it??

 

hold a torch up to it and make it all blue

 

Titanium melts at approximately 3200F, so it probably turns color somewhere between 2500F and melting point...I think. Just a rough guess.

I really don't think your exhaust temps could make it change color. Some exhausts (such as Megan) already have a colored tip.

 

Im sure its a lot colder than that. My friend blues his ARC shiftknob on the stove

 

You're not melting it, your oxidizing it.

 

Ti will start turning oxidizing/nitriding from ~400C up. Higher temp will accelerate the process.

 

Torch It

 

thats funny.....i think i might have to buy one and try that

 

i'd say your flash is a little lean then buddy

haha.

 

Most of the exhaust tips are now a light blue in color.

 

my greddy Ti is nice and blue where it mates up with the test pipe

 

im so checking my greddy ti tomorrow

 

Thanks, that was the answer I was looking for.


As for the type of exhaust; Turbo XS full tbe (stainless, with titanium tip.)

Thanks for the replies.

 

Just in case anyone cares 10 years after the fact...
