Agreed Kenton, but you can use stainless with alluminum.

Why is that, Marcel, They're pretty far apart on the galvanic chart.

I know they are Kenton, but working On a Naval Destroyer, they use stainless with alluminum, but even with painted steel, alluminum has to have electrolic tape applied. It appears that even with salt water, stainless to alluminum does not react.

And I am talking 316 stainless.

Now since the Navy requires and says that is OK, the dictionary seems to say otherwise.
Now I am really confused.

For example, consider a system is composed of 316 SS (a 300 series stainless steel; it is a very noble alloy meaning it is quite resistant to corrosion and has a high potential) and a mild steel (a very active metal with lower potential). The mild steel will corrode in the presence of an electrolyte such as salt water. If a sacrificial anode is used (such as a zinc alloy, aluminium alloy, or magnesium), these anodes will corrode, protecting the other metals. This is a common practice in the marine industry to protect ship equipment. Boats and vessels that are in salt water use either zinc alloy or aluminium alloy. If boats are only in fresh water, a magnesium alloy is used.

I find that in this business, sometimes the more you learn, the less you know.

Ain't that the truth Kenton.
