12L14

Not recommended by any of the steel manufacturers I've got books for.

I often make adjustable brackets and other stuff out of split clamp shaft collars, which are usually 12L14. And while I've never had a weld break, you can sometimes see what appear to be small cracks in the weld, especially near the ends of a bead. I usually TIG with 308SS or inconel.

So while 12L14 is not generally considered weldable, I'd say you can usually get away with it for non-critical, lightly stressed joints.

I'll second that opinion. I've done it too. Non-critical applications being the qualifier.

I have, it didn't look pretty. I want to make some split collars that are joined at right angles to each other for a clamping system as described on this list, I'm going to silver solder them together.

Me three.

I did have a piece blow out after loading it beyond what it should have been loaded to,
