Description
 ASTM A213 covers seamless ferritic and austenitic steel boiler, Boiler Tube, and heat-exchange tubes, designated Grades T5, TP304, etc. Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements.

The tubing sizes and thickness usually furnished to this specification are 1⁄8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if specified in the order, average wall thickness. Tubing having other diameters may be furnished, provided such tubes comply with all other requirements of this specification.

Painting & Coating
（1）Ferritic alloy cold-finished steel tubes shall be free of scale and suitable for inspection,a slight a mount of oxidation is not consideration scale.
（2）Ferritic alloy hot-finished steel tubes shall be free of loose scale and suitable for inspection.
（3）Stainless steel tubes shall be picked free of scale ,when bright annealing is used,pickling is not necessary.
（4）Any special finish requirement shall be subject to agreement between the supplier and the purchaser.
