How large are the gears? How much corrosion resistance do you need?

My first thought was 440 (B maybe?). You don't need a lot of hardness.
How are you making this? Machined? Stamped? Ever thought of powdered metal?

Could the part be fineblanked? If so you might be able to use a duplex stainless like LDX2101 or even 2205. You would have great corrosion resistance and no heat treatment.

RCWAHOO,
I did a similar sounding part (1/4 sector spur gear) for an automotive actuator. We machined the first few proof of concept pieces out of billet, but migrated to powdered metal for the prototypes and then production. We ended up with a custom tailored stainless alloy that was similar to 440B, which is really easy to do in PM. I only had a -40C low temp limit though.
These folks may be able to help you with alloying information in PM:

These are some PM guys that I have worked with
And of course you can contact the tech guys at Crucible, they make a lot of powder for tool steels and stainless.
Though I still like the idea of fineblanking.

Well, they would be close. Another option might be XM-11 cold rolled to 1/4 hard.
What I was really counting on was the cold working of the teeth in blanking.
You may be able to get a duplex with a temper roll pass on it also. I haven't tried to yet.
