Be thoughtful and do some homework with stainless steel structural parts. Much of the stainless world involves annealed 300 series stainless. While it has an ultimate strength somewhat greater than 2024, it has a yield strength that's somewhat weaker than the aluminum.
Still, not all vendors use the annealed 300 series stainless. Some use better stuff.... so please do check.
Also, and this could potentially be an issue, it's not merely the strength you need to consider. Stainless (or almost any steel, for that matter) has a modulus of elasticity that's almost three times greater than aluminum. How does that affect you? It means that if a stainless part and an aluminum one are the same thickness and are sharing a load, the steel one will carry roughly 3/4 of the total load. Yes, there are certain assumptions that go into this estimate, but it's still generally valid. If the structure is designed for that, fine. But if not....
