Are my headers stainless or titanium??

akro ti looks kinda bronzish. that looks kinda stainless steel. but really you should be able to feel the metal and know if its ti or not.
 
Only problem with the grinding test is it gives the potential buyer another reason to try to undercut you saying that you grinded into the exhaust (after they question how you know if it is TI or SS) :laughing

You just tell them you bought the exhaust yourself, so of course you know which it is :)

I have spent 30 years working in SS and Ti - yours look like SS to me.

Ti turns powder blue where the gets hottest, golden where its not quite as hot and stays grey everwhere else.

SS turns tan/brown where it gets hottest and blue where not quite a s hot and stays shiny silver everywhere else.

FWIW high quality thin walled SS headers are pretty much the same weight as OK quality Ti alloy (i.e. Akro' grade not aircraft grade).

The grinder/spark color test is definitive and you can do it with a small Dremmel inside the pipe with a carbide grinding tip. Ti gives an ultra white spark, SS gold to orange.

Alternatively get some metal polish and polish a section to a bright finish, wet it and leave it overnight. The Ti will turn grey, the SS will stay bright.

Cool. I'll remember this one ;)
 
i have a PMI gun at work (positive material Identification) that i can zap it with but it will cost you $145 but you will know within 25 seconds with a full blown certified report and all of the elemental break down of what the metal consists of.....
 
Alright guys, I took it to the shop and we took a dremel to it just to get some sparks. Orange for SS White for titanium right?

And the final results are....................


















ORANGE sparks
 
STOP!!!!!!!!!!!

You don't need to grind. Titanium is paramagnetic - meaning it does not retain a magnetic field on its own, it is only magnetic if a magnetic field is being applied.

MEANING

if you hold a magnet to a Ti pipe, it will easily come off - much easier than if you held it to a stainless steel pipe.

Wait- the grinding wheel used: was it Stainless steel, or was it titanium? :p
 
I bet the grinding wheel was Aluminum Oxide. which when combined with the vanadium in Titanium Alloys like Ti6Al4V, which most headers are made of, gives off a faint yellow spark. was the spark orange or yellow?







OK I'm just messing with ya. at Ti give off a very white spark.
 
Did you clean the filthy fucker yet? LOL
Grinding? WTF?
Any common household bathroom or kitchen sponge has a scotchbrite pad attached to it, use it! SS = HARD. Ti = soft(cleanable). :x :twofinger
