exhaust parts- Is SS dangerous to adjacent steel parts? 200 1991

Hi,

I too question the statement made about stainless steel creating electrolysis in adjacent metals being mounted together or electrically connected.
I went off on a search to get more information about this phenomenon that he wanted to share with us.

Yes , I agree it is very odd to think down that road without considering what he may have meant in an environment of an electrolyte.
Salt water is an electrolyte or at the least a conductor of electricity too.
I also thought of my 240s with their rubber hangers that were put on there as flexible noise isolating units.
I know they do nothing for stopping rust from other corrosive elements involved.

In building something like a battery you need two connections or conductors for input and output.
In the case of electrodes one can become sacrificial.
In his scenario this would be the plain carbon steel parts of the car he is referring to.

Now if adding a stainless exhaust system might acerbate the problem. This would only be by reducing the amount of eatable material available.
So that would make the any other parts even more susceptible to corrosion under electrolytic conditions of snowy road or driving on an ocean side beach in a blink.

In conclusion, I do not want to dismiss his post into the lands of total poppyseeds as I had one critic say about a post “I must be smoking something good.” 🙂 I don’t drink or smoke as I have enough going on without any help.🤭

I can appreciate opinions. As like on other things from our bodies, everyone has at least one something out of necessity. It keeps the world interesting.

Thanks for your post now I feel better about doing my research.
The idea of a ceramic paint or better yet, ceramic exhaust systems.
That sounded entertaining as catalytic converters use ceramics.
Just need something not so brittle as porcelain used earlier cooking pots and then lose the metal substrate.
How to keep it light and of course cheap, would probably kill the project. ICE contraptions are on the endangered lists.

Hey, we have fiber optics now, just installed in my house, because of thinking out loud among our cohorts.
