ASTM A213
ASTM A213 is an important standard developed by the American Society for Materials and Testing (ASTM). The ASTM A213 standard focuses on seamless ferritic and austenitic alloy steel boiler, superheater and heat exchanger tubes under high pressure and temperature.
ASTM A213 standard tubing is manufactured in a seamless process with excellent corrosion resistance and strength. The most common materials are alloy steel pipes and stainless steel pipes.
ASTM A213 contains a variety of steel grades to facilitate applications in different environments. Some of the common grades are: ASTM A212 Grade T2/ T5/ T9/ T11/ T22/ T91. The main difference between these grades is the chromium and molybdenum content, with the lower grades having lower oxidation and high temperature resistance. T91 consists of 9 per cent chromium and 1 per cent molybdenum, with traces of vanadium and tungsten, and is ideally suited to supercritical boiler applications.
Steel Grade of ASTM A213
The ASTM A213 standard has different chemical composition and performance requirements for each grade.

DIMENSIONS AND SIZES OF ASTM A213 PIPE
The ASTM A213 standard has a very comprehensive size range. Inside diameters range from 1/8 inch (3.2 mm) to 5 inches (127 mm), while minimum wall thicknesses range from 0.015 inches (0.4 mm) to 0.500 inches (12.7 mm).
The ASTM A213 standard strictly controls these size ranges of tubing, ensuring that the tubing produced can be accurately and perfectly adapted for both sophisticated components and large-scale project applications.
| Outside Diameter： | 1⁄8 to 5 in. [3.2 to 127 mm] |
|---|---|
| Wall Thickness： | 0.015 to 0.500 in. [0.4 to 12.7 mm] |
| Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification. | |
CHEMICAL COMPOSITION REQUIREMENT OF ASTM A213 PIPE
The ASTM A213 standard has very strict requirements for chemical composition. The content and proportion of each chemical element will directly affect the final performance of the steel pipe.
- Carbon (C) : Usually between 0.05% and 0.12%. It affects the strength and hardness of steel.
- Chromium (Cr) : The chromium content in ASTM A213 tubing is generally 1% to 12%. The high temperature resistance and oxidation resistance of steel are affected.
- Molybdenum (Mo) : Generally between 0.25% and 1%. It affects the high temperature strength and creep resistance of steel.
- Manganese (Mn) : Usually 0.30% to 0.60%. It affects the strength and hardness of steel and improves its wear resistance.
- Silicon (Si) : Generally between 0.20% and 0.50%. It affects the strength and hardness of steel.

MECHANICAL PROPERTIES OF ASTM A213 PIPE
The ASTM A213 standard has clear requirements and regulations for the tensile strength, yield strength, elongation, etc.
- Tensile strength: Taking T11 as an example, its tensile strength should not be less than 415MPa. High tensile strength can make the steel pipe under high stress and load is not easy to fracture and deformation.
- Yield strength: Taking T11 as an example, its yield strength should not be less than 205MPa. The yield strength is generally treated by heat treatment processes such as quenching and tempering.
- Elongation: Taking T11 as an example, the elongation after breaking should not be less than 30%. The toughness and plasticity of the pipe were improved by optimizing the uniform and fine grain structure.

1. What Is the Difference between ASTM A269 and A213?
- ASTM A269 is suitable for piping systems requiring high corrosion resistance. A269 covers austenitic stainless steels but excludes ferritic alloy steels.
- ASTM A213 is the standard for boiler tubes, addressing ferritic alloy steels and austenitic stainless steels in high-pressure environments.
2. What Is the Equivalent of ASTM A213 T11?
ASTM A213 T11 is a typical low-alloy, high-strength heat-resistant steel.
Its equivalent materials include JIS STBA22 / STPA22, ASTM A335 Grade P11, EN 10216-2 Grade T11, etc.
3. What Material Is A213 TP304?
ASTM A213 TP304 is an austenitic stainless steel. The letters TP denote its type. Its carbon content is ≤ 0.08%. Chromium content of 18.0–20.0% enhances the material’s corrosion resistance and oxidation resistance.
