What is ASTM A213 Standard?

ASTM A213 is an internationally recognized specification for seamless ferritic and austenitic alloy-steel tubes used in high-temperature services. Its scope includes grades such as T11, T22, T91 (ferritic alloy steel) and TP304L, TP316L, TP347H (austenitic stainless steel), which are chosen based on performance needs.

Core Requirements

Seamless Manufacturing: Tubes must be produced without welds using either hot rolling or cold drawing.

Heat Treatment: All tubes must undergo solution annealing (for austenitic grades) or normalizing and tempering (for ferritic grades).

Corrosion Resistance: Austenitic grades such as TP316L and TP347H offer excellent corrosion resistance, especially against chlorides, acids, and high-temperature oxidation.

Testing: Tubes are subject to 100% non-destructive testing (NDT), including:

Hydrostatic test or eddy current test

Tensile strength and yield strength test

Hardness and flattening tests

Intergranular corrosion test (for grades like TP347H)

Material Grades & Properties

Ferritic Alloy Steel Grades (T11 / T22 / T91)

Grade	Key Elements (%)	Tensile Strength	Yield Strength	Max. Hardness
T11	Cr 1.0–1.5, Mo 0.44–0.65	≥415 MPa	≥170 MPa	≤163 HB
T22	Cr 1.9–2.6, Mo 0.87–1.13	≥415 MPa	≥205 MPa	≤163 HB
T91	Cr 8–9.5, Mo 0.85–1.05, V 0.18–0.25	≥585 MPa	≥415 MPa	190–250 HB

Applications: Ideal for supercritical boilers, fossil fuel power plants, and high-pressure piping.

Austenitic Stainless Steel Grades (TP304L / TP316L / TP347H)

Grade	Key Elements (%)	Tensile Strength	Yield Strength	Features
TP304L	Cr 18–20, Ni 8–12	≥485 MPa	≥170 MPa	Low carbon for intergranular corrosion resistance
TP316L	Cr 16–18, Ni 10–14, Mo 2–3	≥485 MPa	≥170 MPa	High pitting resistance; suitable for marine use
TP347H	Cr 17–19, Ni 9–13, Nb stabilized	≥515 MPa	≥205 MPa	Superior creep strength at up to 900°C
