You should be able to find SS washers at Home Depot although they may be listed as something other than 1 1/2 and 2 " washers because they measure the size by the hole in the middle and not the actual diameter of the washer.
The diameter of the washer must fit over the Cage bars easily, firmly and securely. This is a MUST. The hole in the center must fit perfectly as well.Did you mean you are looking for a washer with a 1 1/2-2 " hole in the center or that's the actual size of the washer across you are looking for? what do you need it for? If the item you need the washer for isn't too large I would take it with you into the store so you make sure you get the correct size.

You can search by both inside & outside diameter as needed.
These are the ones I got for use with the booda perches: 7/8" inside hole, 2" outside diameter

Thanks Merlie and Trout. Will bring needed washers to my local hardware stores to purchase what I need.You shouldn't have any problem finding the washers you need at decent hardware store. I don't much use SS washers anymore, I much prefer the Poly Carb washers at bird on the rocks, I just like the way they look.
I couldn't find what I wanted locally so had to look onlineThanks for the link Gg!
I imagine that I should be able to purchase any kind of stainless steel washers locally.
