I don't know what point you are trying to make here, but it looks very negative.
I was trying to be polite.
Bronze has never been a stainless steel, you see. Stainless is nprmally shiny (not always) and bright. Bronze has a coppery look about it. Bronze has lots of copper and tin in it, stainless steel does not... the chrome makes it shiny if you polish it. Indeed I have been on my boat and had a bonmze fitting in my right hand, and a stainless chainplate in my left. The bronze (to the right as I looked) kinda looked yellowy. The stainless (to the left as I looked) was all shiny like... you could see your face in it you see. I have witnesses too. Indeed there were three of us, and the other two nodded when I said that they looked different. Bronze it like that you see... the copper in it makes it look sort of yellow.
The prop shaft on my boat is all shiny like, and it's not yellowy. It's got a big pit in it too. That's where it was starved of oxygen in the presence of salt water (chlorides, like). It's not a crack... it a big pit. Keelbolts are like that, they tend to get wet and boats go out in the sea... salty, like. Keelbolts lile in bilges, bilges are wet, bilges often get oxygen starved.
I have a bolt that served for a while as a fastener for the sternplate. It's virtually eaten through, and still shiny. It's like 3/4" thick. It's stainless. It's not the stuff I'd dare use for keelbolts. Maybe duplex would work, but not that stuff.
