I was working on my car... doing oil change. And I had to change the gasket on my exhaust. I am running tanabe medalion touring... I noticed something, I had a magnet lying around next to me and I tried to stick it on the exhaust. Just like my oem and other aftermarket exhaust... the magnet won't attract with the medalion touring.

What gives? Is this a bad thing or what? What the heck is this SUS304 means anyways...

 

its stainless steel

 

Many many metals are not magnetic: http://www.newton.dep.anl.gov/askasc...5/phy05054.htm

 

not all stainless steels are non-magnetic. Most 400series stainless steels are magnetic due to their high steel to chromium content and presence of no nickel. Your exhaust is 304/304L stainless steel which is in the 300 series stainless category and exhibits excellent weldablity and formability along with good corrosion resistance. However, when they are work(bent on a mandrel) excessively they can become magnetic.

 

^^That's some good knowledge right there Rambo, thanks

 

Interesting... That's a good knowledge. I didn't know about that. So next time i get new exhaust I'll have magnet in hand to see how good quality they are lol...

 

mcmaster-carr.com also has good background info on different metals
