1. Rationale
WK34129 revised the location of footnotes to Table 2, Chemical Requirements, but introduced an error for the nitrogen contents of grade F304L, UNS S30403. This has since been published in A182/A182-12a and a user has requested that the error be corrected. Since the error was introduced by a ballot item, it cannot be corrected as errata by ASTM staff: it must be corrected by a ballot item. The objective of the WK34129 action was merely to eliminate footnotes I and J and to put the chemistry requirements of those notes into the table. There was no intent to change the chemistry requirements. The notes in question used to read: IGrades F304, F304L, F316, and F316L shall have maximum nitrogen of 0.10%. JGrades F304N, F316N, F304LN, and F316LN shall have a nitrogen content of 0.10 to 0.16%. That is, for the straight and the L grades of 304 and 316, the N should be 0.10% max; while for the N and LN grades, the N should be 0.10-0.16%. So, the value for N in Table 2 for F304L, in A182/A182M-12a, is incorrect. This action corrects the nitrogen content of F304L.
