unless you know the alloy and how it was made, you have no idea how it will react to what you are planning to do to it.
there are literally thousands of alloys available to any manufacturer of metal parts. steel is not just steel.
so trust your favorite manufacturer for doing his homework and picking the best material for the application at hand, and go make some holes in paper.
