I have been doing a little research on the welding forums and the net in general and I am (very) slightly surprised that pretty much everyone is saying is ok, fine or even better to weld 304 with 316 rod for various reasons that range from misguided to compleatly insane.
Generally, the use of an “overmatched” filler ( a crapy description to begin with) is standard practice, but the one thing you almost NEVER want is a weld that has LES ductility than the material welded.
ER316L is NOT “better” just because it is a bigger number that ER308L!
316 is generally harder, more brittle, and more likely to crack than 304 or 308. It IS the right rod to use for, surprise! 316
308 is the filler for 304, and yes most of the time you can get away with using 316 just fine, but I think it is a lazy, poor practice to use it routinely and worse to say it’s fine, and plain stupid to say it’s better.
Well, what do you think?
