The indication as used in EN 10088-2 is: X2CrNi19-11
RE: EUROPEAN EQUIVALENTS
The 304L grade was split in two to take into account different nickel contents:
Steel number 1.4306 has the name X2CrNi19-11 (as you pointed out) and the lower nickel variant (which is preferred by suppliers because its lower nickel content means it is cheaper)is Steel number 1.4307 and has the name X2CrNi18-9. 1.4306 has a slightly higher chromium content too.
From the name you can tell its nominal composition. The number following X is roughly the mid-point of the carbon content range times 100; the 18-9 is the respective nominal content of the chromium and nickel. The steel number is usually quoted rather the name because, as the number of the elements in the steel increases, the name becomes unwieldy.
