I work as a Lab Mgr in a large university, formerly an ME doing
fossil-fueled combustion stuff.
Our undergrad student chapter of SAE builds a small formula-type racer
and competes with other chapters. They want to modify the design of the
half-shaft axles but are having problems finding the material they have
used in the past (4340).
Can someone suggest an appropriate substitute? I'm thinking 4140, but
don't know about availability.
