How you test for steel wheel or ceramic?

How do you test for this?

 

i have some turbos here that are suppose to be steel wheel upgraded.

Have a look: steel looks just like steel

There's no such thing as a steel wheeled turbo.  They're at least some sort of high grade stainless, up to inconel.  Not steel.

The best test is to hit the turbine with something like a small ball pein hammer, screwdriver, chisel, etc.  If it breaks, then it was ceramic and needed to be upgraded anyway.

20psi for a while should do it.

They love 25psi. That's the sweet spot

use an angle grinder and read the spark shower!!!

Here's one I prepared earlier. If it looks like this, it's ceramic.

Run a small bolt through your engine. That's how I "did" mine ¯\_(ツ)_/¯
Only real way of knowing is boosting it until the wheel falls off, or blows your engine.

Or take the turbo off and look at it

seriously man, just search. covered many a time.

a long time ago, Jesus invented magnets, after he killed off the dinosaurs, and then removed any mention of them from the Bible. A magnet may or may not work.

600 series Inconels are not magnetic. Austenitic stainlesses are also not.  There may be some stainlesses (ferritic ones) used for turbines that could be magnetic, but in general I wouldn't be making any decision on whether it's metallic or ceramic based on a magnet test.  Sadly.

and if they're in the car still buy one of those usb endoscopes off ebay for 12 bucks and shove it up the front pipe.

one has that guitar pick looking nut and the other has a normal nut which was looks like half of it shaved off, I guess for balance. my ceramic wheels look lighter in color that came off my car and these look different. guess they are steel wheeled.

 

as mine here are rebuilt with steel wheels I was looking for a more exact way of knowing other than smashing it with a hammer or a magnet because magnets will not stick to either.
