The complexities of metal naming are rediculous... But here is a brief primer.

18/8 and 316 are determined by different standards bodies, so there is not a rule that translates between the different organizations.

Secondly 18/8 and 316 are really a group of alloys, not a specific one. Hey refer to any alloy that has the minimum characteristics demanded, and the maximum demanded. But could vary significantly otherwise.

18/8 refers to a group of alloys that have a minimum of 18% chromium, and 8% nickle.

316 refers to the group of alloys that have A minimum of 16% chromium, 10% nickle, 2% molybdenum.

Both have a host of other requirements, and trace metal allowances but those are the major differences.
