Shimano FD cages are not stainless.

That said, others have noted plating issues:

It appears to be stainless steel. https://metalexponents.com/blog/factors-corrode-stainless-steel/ That these FD7800 front derailleurs started flaking the chrome off almost immediately should give you a clue - chrome does RUST off of plain steel but it does not corrode off. And you can't tell the difference with a magnet since many grades of stainless steel are magnetic. That is due to the percentage of steel contained in the alloy.

So, you may be correct but what then is it that makes the FD strong enough to wear so well and yet corrode?

All of them? I’m pretty sure my FD9070 is stainless steel, it is not chrome plated like my GRX FD.

Never let it be said that Shimano doesn't learn from their mistakes. Polished stainless looks good but you can tell the difference between stainless and chrome at a glance.

Mweh, polished stainless can look very shiny. I did an internship at a manufacturer of chicken slaughter machines and they treated all of there stainless steel parts that had a high chrome content. They looked almost like chrome plated.

Yes, but it would NOT corrode and peel the Chrome off in plainly visible layers https://www.ebay.com/itm/325414974693?hash=item4bc43e74e5:g:X0MAAOSwgBljaSHX&amdata=enc%3AAQAIAAAA4D7bpIlnlMWSBXB5NvtL3enue%2BT1JevmbNv4d9qMwtHnTUQfVooN69%2Bk65b6KLWH1kEORJMBviDIA7iN5ekiDX5DxK5Ea4mBbtx%2FBigr3cSvdiv4R1d8r4Eapyh41z1xOjShCBn18XzwlhiTP%2F6mzRpyc1FJVSKvwa8YtqOjqs8whcRUhg7p%2F7sXBCQGamtOQuQQ4kszKeTGwmERd7%2FbQ3iYPNVcrguVhGn10Mmaee8HvVr%2B1muizk3mnv1%2B1a1yM1w9qu7cD4WoXrwVd9VvzTutGpl3IfISBM5qsg5uHQYQ%7Ctkp%3ABk9SR4C6qMiFYw

Oh, sorry you are right. I meant Mr Kunich's FD-7800 not
'all Shimano FD'.

'Looks good' to you, which is fine.

The various stainlesses can show a multitude of finishes,
for example:

https://www.tesla.com/cybertruck

(which does not shift, BTW)

Stainless surgical tools are usually polished as shiny and
smooth as anything chromed.

A fairly common "make up" of "stainless steel" is 0.015 to 0.10%
carbon, 16 to 21% chromium, 6 to 26% nickel, 0 to 7% molybdenum.

Of course it is Chorus rather than Record but I haven't been able to tell the difference except for a couple of ounces difference in weight. Super Record is detectably lighter but meager ounces hardly is going to make or brake a build.

Andrew, I'm still waiting for what you believe the FD 7800 to be made of. Stainless of some types rusts just like normal steel but usually spotty. The back of an FD 7800 does exactly that. And chrome sticks fine to regular steel but not to stainless - just like on the FD 7800.

BTW, I now have no sources of parts with my bowing out of Paypal, Amazon and Ebay. Craigslist is too spotty. I am looking for a set of 1" carbon spacers and a 1" carbon fiber expander for the new fork. cyclintom@yahoo.com

Wrong (as usual). The Dura-Ace 7800 front deraaileur cage is nickel
plated:

"Plus, the lightweight, replaceable aluminum cage is nickel plated for
durability."
More links that say basically the same thing:
