Mild steel is not alloy steel and therefore does not contain large amounts of other elements besides iron. You will not find vast amounts of chromium, molybdenum, or other alloying elements in mild steel.
No mild steel is not rust proof.
Mild Steel also has excellent fatigue resistance, meaning it can handle even the most extreme stress cycles without any lasting damage. Hence, mild steel is used for car bodies.
Yes, mild steel is stronger than aluminium.

Mild steel can withstand high tension without breaking because its ultimate tensile strength ranges from 340 to 440 MPa.
Some of the machine's I am familiar a wee bit with have shearing ratings given in material TENSILE STRENGTH versus THICKNESS.
A specific machine example is:
For instance 50,000psi material cutting capactiy of 9/32 - however 100,000psi material cutting capacity of 3/16
So it ISN'T appearing quite as simple as plain old simple math - BUT keeping it conservative and using common sense will probably keep you out of trouble!
Another example is that if you look in Machinery's Handbook they list (at least my 14th addition does) SHEAR Strength which closely resembles TENSILE strength BUT NOT exactly - some materials have shear numbers HIGHER than TENSILE numbers while other materials are the other way around!
FWIW they list Stainless(and plain old steel) as having the SAME valusies both Shear and Tensile (Steel is different than stainless number wise - but the SHEAR and TENSILE numbers are same for EACH - for instance Stainless might list 120,000psi shear & Tensile while mild might be 60,000psi shear and tensile.
BUT!!!! WAIT!!!!!
Most machines give ratings as "MILD STEEL" which is QUITE a bit lower than OTHER forms of steel (50-60K (psi) - ALLOY steel may be TRIPLE the TENSILE rating - STAINLESS might be quadruple of double or ??? It ALL depends on the ALLOY and HEAT TREAT.
So unfortunately your answer is gonna require some additional research on your part in terms of material - remember the "factory" likes to give ratings in the most "favorable" light.
Another typical rating is my hand held nibbler - rated 10 ga. Steel (mild) and 12ga Stainless (304??) - while another one is 10ga and 14ga respectively - go figure.
I doubt this was the kinda answer you were looking for, but hey I tried!!
Good luck!
