You were right. 316 is a bit weaker than 304 but is more corrosion resistant. This is one of those cases where you have to be careful about info gleaned from the web. I have seen actual tables on the web that showed 316 was stronger but it isn't.

As a VERY rough rule of thumb, constituents in alloys that improve corrosion resistance (chrome, nickle) either don't increase it's strength or actually weaken it. Constituents that strengthen it (carbon) reduce its corrosion resistance.
