Description:

(A) Maximum, unless a range or minimum is indicated. Where ellipses (...) appear in this table, there is no minimum and analysis for the element need not be determined or reported.

(B) The method of analysis for Nitrogen shall be a matter of agreement between the purchaser and the producer.

(D) For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.040% is necessary in Grades TP304L, TP304LN, TP316L, and TP316LN.

(E) Grade S30434 shall have (Ti + 1/2 Nb) of not less than 2 times and not more than 4 times the carbon content.

(F) Grade TP347LN shall have an Nb content of not less than 15 times the carbon content.

(G) Grade TP348 shall have an Nb + Ta content of not less than 10 times the carbon content and not more than 1.10%.

(H) Grade TP348H shall have an Nb + Ta content of not less than 8 times the carbon content and not more than 1.10%.

(I) Iron shall be determined arithmetically by difference of 100 minus the sum of the other specified elements.

(J) Al + Ti shall be 0.85 % min; 1.20 % max.

(K) Grade TP444 shall have Ni + Cu = 1.00 max.

(L) Grade TP444 shall have Ti + Nb content not less than 0.20 + 4(C+N) and not more than 0.80 %.

(M) N08020 shall have an Nb + Ta content of not less than 8 times the carbon content and not more than 1.00%.
