What to know before ordering to ASTM A213
The points that decide whether material to ASTM A213 is accepted at inspection.
- Tubes are ordered by OD and minimum or average wall thickness.
- The "TP" prefix denotes the tube grade, for example TP316L.
- Hydrostatic or non-destructive electric testing is required on each tube.

How ASTM A213 fits into an order
A purchase order line is only complete when it names the material standard, the dimensional standard and the inspection document. Miss one and the mill, the inspector and the buyer can each read the order differently.

ASTM A213 — questions buyers ask
What does ASTM A213 cover?
Covers seamless ferritic and austenitic alloy steel tubes for boilers, superheaters and heat exchangers, including stainless grades such as TP304, TP316L, TP321 and TP347.
Which grades do you supply to ASTM A213?
SS 304, SS 304L, SS 310 / 310S, SS 316 / 316L, SS 321, SS 347 — see the table on this page for the exact product and designation.
What is the difference between ASTM A213 and ASME SA-213?
ASME SA-213 is the ASME Boiler and Pressure Vessel Code (Section II) adoption of ASTM A213. The technical requirements are usually identical to a specific ASTM edition; pressure-equipment codes call for the ASME designation, and most mill certificates show both.
Do you supply certificates to this standard?
Yes. Material is supplied with mill test certificates to EN 10204 3.1 showing the standard, grade and heat number; 3.2 with third-party inspection on request.
