Your stainless rivets are more noble than your aluminum mast and the area ratio is in your favor. It may not be "perfect" - but it works. dj
To get to the root of your problem, you need someone to be able to look at your specific boat, in it's specific location. There are indeed a lot...
@alby joy - Looks from your profile that you are in India. I don't know what organizations you have there, here in the USA we have ABYC that has...
As I found the original question in this thread really fascinating, I decided to ask at the Smithsonian's Air and Space Museum if they may have...
Kinda there, there are typically three kinds of rust in the steels you are talking about, Fe2O3, Fe3O4 and the FeO. (this is a simplistic...
That's a good point, but if it's the outside surface of that nut, not the interface between the two, what mechanism do you suggest?
I was just reviewing this thread and am not clear which surface on the nut you are seeing this degradation. [ATTACH] Is it on the outside towards...
Yeah, sorry, I hear all the time people saying that "good" stainless steel is non-magnetic and "bad" stainless steel is magnetic. It's just not a...
The issue is not passivating the nut, it's maintaining the passive layer. That maintenance is the problem. That is where you need to make sure you...
I'd suggest you purchase some 1/2 hard 316 alloy per ASTM 666 and stick a magnet on it. [ATTACH]
sigh.... [ATTACH]
Apologies just saw this. I can quote some parts I guess, but i'm not sure how much is permitted by copyright laws. Here's what is says about...
AISI 316 if cold worked is quite magnetic. Sorry for your misinfomation.
Another thing to point out. the OP said it was stainless steel, but that may well not be the case. It very well could be chromium on top of...
Looking a bit more at your design, I'd recommend you change out your nuts from 316 to 17-4 PH in the H1000 condition, or higher. I would not use...
That is not the case. Read AMS 2460 - it provides some basis in their differences. In addition, we don't know what they did in the manufacture of...
I would agree with this. I would also add that these grades of stainless steel should not be used in submerged applications unless you are...
This is not correct. Both 304 and 316 are austenitic stainless steel alloys and both can be magnetic or not. In the annealed condition, neither...
WWII hydraulic rams were typically chromium hard coat plated. Not a decorative type coating, but a functional coating. The functional coating...
