I've found the differences in both the metals (the 316 having 2-3% molybdenum). im going to be making a turbo manifold and the 316 elbows are only like $2.00 more than the 304 elbows so i was thinking why not go with the 316. i don't recall ever seeing anyone use 316 sch 40 for a turbo manifold thats why i am asking. some insight would be great, thanks
