Where 316 fits
Why 316 is special
That addition is what makes it hold up in seawater and chlorides, which is why marine and food equipment specifies it over the cheaper grade.

Binary

1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 1 × 16 + 1 × 8 + 1 × 4 + 0 × 2 + 0 × 1 = 316

4 × 64 + 7 × 8 + 4 × 1 = 316
Hexadecimal
1 3 c
1 × 256 + 3 × 16 + c × 1 = 316
Read as powers of two: 256 + 32 + 16 + 8 + 4 = 316.
In historical numeral systems
Egyptian
3 coils of rope, 1 hobble, 6 strokes
3 × 100 + 1 × 10 + 6 × 1 = 316. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 1 corner wedge + 6 vertical wedges (units place)
5 × 60 + 16 = 316. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then iota, then stigma, marked as a numeral
tau-iota-stigma + keraia
tau + iota + stigma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then tet, then zayin
shin-tet-zayin
The ordinary rule would give יו (yod 10 + vav 6), also a divine-name form, so 16 is written טז — tet (9) + zayin (7).
Maya
3 bars (upper, twenties place) over 3 bars + 1 dot (lower, units place)
15 × 20 + 16 = 316. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Higher nickel, molybdenum and copper extend acid resistance well beyond what 316 offers, at a cost that limits its use.
