I'd like to know why it won't work as well. That nsx thread says otherwise. You care to elaborate?

 

it might but i can tell you i tried it in highschool with jewlery i was making in class and it didnt burn it turned a dull gold. the reason it worked on the lexus forum is because HKS puts a titanium sleve on the ends of their exhausts. i can't see the pic's on the NSX forum but if they are HKS they are probably TI sleves on the end.

 

I know it's Wikipedia, but still worth a read:
http://en.wikipedia.org/wiki/Bluing_(steel)

Basically, you're looking at converting the iron in the steel to Fe3O4 on the surface. Stainless steel is still mostly iron, but has a high chromium content. As long as it's heated to the proper temperature it should take. The caveat is that for the surface to oxidize properly, you first need to break the passivated chromium surface barrier, i.e. polish the crap out of it to clean off the chromium oxide surface layer, and do heat treatment quickly before a new layer forms.

Just FYI, "stainless" steel isn't stainless, just corrosion resistant. If you scratch the surface and leave it underwater where it doesn't "heal" by forming a new oxide barrier, it will rust (Fe2O3 vs. Cr2O3 in air)

 

Thank you! Not that the rest of you haven't been helpful but this is what I'm looking for. As a longtime gun owner I understand that stainless steel isn't stainless. I'm going to polish the heck out of the tip beforehand, then do the burning. We shall see how this turns out! Should be very interesting.

 

watching.

 

stainless has a certain nickel content depending on the grade. This makes it corrosion resistant

This method might work on some garbage stainless but not good quality stuff

 

The NSX thread was done on a Taitec GT exhaust. From the translated page, there is no mention of titanium in the tip, and given that the exhaust costs about 90k yen or $1,000 USD, I doubt it's crappy stainless.

Let the man try it, it's a free mod, and see what he comes back with. Worse case if it comes out all gold just polish it back out.

 

i'm not saying don't try it because seriously if it works i'm doing it to my ptuning exhaust.

 

Well my exhaust is $150... Worth trying it on

 

i suppose i could try it on my Concept G that isnt on my car. it's just collecting dust in the garadge.

 

I plan on doing it this saturday. And I have to do it now, because Spicy_Mcwhatever said it won't work.

 

definately watching this..

 

Note that I'm not the only one who said it won't work.

It will be labor intensive trying to get a very sheen polish on it before trying to burn it. Its fine and dandy if you go for it, I'm simply saying with my experience in Stainless Steel that it won't give you the look you want. (I work with metals everyday at work, Stainless being a major one. I could care less if I'm your motivation or if you listen to me. Its your car)

Edit: Theres a BIG reason why the burnt tip look is on Titanium 99% of the time, it gives the look you want.

 

I should try it on my Tsudo N1. Anyone got a blow torch and metal polish? Lol

 

I've been pretty extremely busy so this is on hold till spring break... So in a week.

 

Just learned it in my Material Science course, the portion that makes the steel "stainless" is the chromium content. A certain, minimum amount of chromium must be present to prevent corrosion. You're right though, nickel can also be added to the steel alloy, to give the steel certain properties.

 

What happens if you decide you want to clean your exhaust and polish it up but still wanting to keep the burnt tip look? I remember seeing someone polish their exhaust just to clean and make it new again but they went over their burn tip and it turned a goldish color.

 

yeah ill have to look more closely but i think my greddy ti-c is turning a slight gold color from me washing it just with soap but it looks pretty sweet

 

Any updates?

 

No; I'm doing it this coming monday or tuesday. I'm just too busy right now. Next week is my spring break.
