I think I've asked this before, so a SS gas tank really is not that different than a mild steel one, and building one with SS and the terne process coating, is for assembly, not really for protection of the tank from gas, water, rust and such.

Just asking to learn, and maybe some other readers might gain knowledge from this too. I'll be looking for the book too.

TX in advance!

SS cannot be terne coated, and does not need to be as it has good corrosion resistance after being formed and soldered into gas tanks.


Only mild steel can be or needs to be coated with terne. Terne makes the mild steel easy to solder while adding very good corrosion-resistance at the same time. Plastic (ABS) has replaced terne plate for auto fuel tanks in the US, as well as in other countries. (I've welded ripped ABS tanks using a 275w soldering iron and slices of another ABS fuel tank.)
