5. Mark of A213 TP201 Chemical elements
AMaximum, 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.
BThe method of analysis for Nitrogen shall be a matter of agreement between the purchaser and the producer.
CFor these alloys, there is no common grade designation. The UNS number uniquely identifies these alloys.
