Nah, they’re just Harbor Freight cheapo balls. All stainless balls are like $60, plated ones are like $20. It doesn’t take much for the plating to wear off from a trailer, and then there’s no stopping the rust.
I’m no expert, but I’m not saying it’s stop the rust, just rub it off. Rust is a thin layer on the outside, and it comes off really easily. I assume actually hooking up a trailer and using it on occasion would wear the rust off (for a little while). I could be totally wrong though.

I can confirm that scraping the balls causes rust way faster than it might scrape off. If you see glossy balls, they are likely never used.
