The short answer is Yes.
Err, maybe... All I am getting is name and Density outside of Inventor.
But when I open the STEP in Inventor I get all of the Material Properties.

Use 214 or 242.
Unfortunately not all CAD software can pick up the Material information...
And of course - as mentioned previously Material (properties) and Appearances are two different things.
And of course - you can do your own simple experiment within Inventor and with other software opening the STEP file.


I guess I should have matched up the Units in my test, but you get the idea - you can run a test.
