3. SA213 TP201 Stainless Surface Condition
Ferritic alloy cold-finished steel tubes shall be free of scale and suitable for inspection. A slight amount of oxidation is not considered scale.

SA213 TP201 Ferritic alloy hot-finished steel tubes shall be free of loose scale and suitable for inspection.

SA213 TP201 Stainless steel tubes shall be pickled free of scale. SA213 TP201 When bright annealing is used, pickling is not necessary Any special finish requirement shall be subject to agreement between the supplier and the purchaser.

5. Mark of SA213 TP201 Stainless pipe 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.

DFor 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.

EGrade TP347LN shall have an Nb content of not less than 15 times the carbon content.

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

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

HGrade TP444 shall have Ni + Cu = 1.00 max.

IGrade TP444 shall have Ti + Nb = 0.20 + 4(C + N)–0.80.
