i don't know but my personal carry lg seb 21 has been around since 1997 and still works like it was brand new and it is BG 42 steel.... i do take it apart and clean it every 6 to 12 months or so... if i cut an orange etc i rinse it in with fresh water when done... any blade steel can corrode if not cared for.......... S35VN is good blade steel better than BG 42 ...

Thank you for sharing your experience, ti lock.
It seems that empirical evidence suggest CRK grease does not yield issues like OP had, even if a knife is not frequently disassembled. Then, as kidcongo suggested, the cause might be nano-oil in this particular case.

From the same owner, a small Sebenza made in 2014.
Disassembled & cleaned for the last time in January 2016, and put together using 85 as well as 10 weight Nano-Oil.
Has been used to cut a lot of cardboard boxes as well as 5 oranges a day since then, and was rinsed afterwards under a hot tap, never disassembled.
Just took it apart for the first time again.
Corrosion on the pivot area of the blade is less than on the Sebenza 25, but the bushing has suffered quite a lot.

Holy Smokes! No more nano oil! It's not doing it's job.
Not at all. CRK says that oils aren't recommended, your pictures supply the proof.

straight from ChrisReeve.com.
I don't think it matters too much which you use. I think the knives were subjected to A LOT of OJ, that's why they got as bad as they did. 5 oranges a day for a year is like 1825 oranges! That's a lot of juice! The grease would have resisted being washed out under the hot tap better I'd think though, so there's that
The CRK site also says this -
"Should you wish to lubricate the pivot, use a Teflon lubricant- our Fluorinated Grease is recommended for this purpose."
The different answers in the FAQ are not in agreement, like the site needs to be cleaned up. The one I copied is, I believe, more recent.

ti locks' Large Sebenza 21 has the CRK flux capacitor option. You don't have one of those LW?

I've used BreakFree CLP in my Sebenza, which is a Teflon lubricant, without issue. Wouldn't that be "in-spec"?
To the best of my knowledge, fluorinated grease is teflon grease or at least contains telfon to a large degree.... breakfree is a type of gun oil...

I meant the rust, which has already been developed like in the OP's case.
I would agree that grease slows down further growth of rust by limiting oxidation. But it wouldn't stop the process.
I was thinking if the rusted part of the steel should be treated with citric acid or nitric acid to remove free Fe and for reformation of the "stainless" chromium oxide layer.

soak the blade in kerosene overnight... clean effected areas with fine steel wool if need be... clean and coat with good gun oil "rem oil" for example, wipe clean... apply fluro grease to appropriate pivot area, bushings, reassemble ...
