Stainless spokes are subject to stress corrosion cracking. Stainless is not good a ggod application under tension. So stainless spokes can just start to go on you after a few years..

Carbon steel doesn't have this problem and can also have a higher tensile strength. As far as corrosion, I have wheelsets that are 70 years old that look ok. These are track wheels that never saw salt though. My experience is that carbon steel spokes just don't have the problem of starting to snap at the bend after 3 years.
