ASTM A213 T9
ASTM A213 T9 - industrial steel pipe
ASTM A213 T5 seamless tubes are manufactured from chromium molybdenum alloy steel for high-temperature boiler, superheater and heat exchanger applications requiring reliable mechanical performance.
ASTM A213 T5 tubes are seamless ferritic alloy steel tubes designed for high-temperature service applications including boilers, superheaters, heat exchangers and power generation equipment. Manufactured according to ASTM A213 / ASME SA213 specifications, these tubes provide excellent resistance to oxidation, corrosion and thermal stress under elevated temperature conditions.
The T5 grade contains chromium and molybdenum elements, which improve high-temperature strength and creep resistance compared with conventional carbon steel tubes. ASTM A213 T5 seamless tubes are widely used in petrochemical plants, thermal power stations, refineries and industrial heating systems.
ASTM A213 T5 alloy steel tubes are produced by a seamless manufacturing process to ensure uniform wall thickness, reliable mechanical properties and excellent pressure resistance. The tubes are supplied with heat treatment according to ASTM requirements to achieve the specified hardness, tensile strength and microstructure.
ASTM A213 T5 tubes are commonly used in high temperature equipment where strength and oxidation resistance are critical. Typical applications include:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.15 max |
| Manganese (Mn) | 0.30-0.60 |
| Phosphorus (P) | 0.025 max |
| Sulfur (S) | 0.025 max |
| Chromium (Cr) | 4.00-6.00 |
| Molybdenum (Mo) | 0.45-0.65 |
| Property | Requirement |
|---|---|
| Tensile Strength | 415 MPa min |
| Yield Strength | 205 MPa min |
| Elongation | 30% min |
| Specification | Description |

Sunny Steel supplies ASTM A213 T5 seamless alloy steel tubes with complete quality documentation including material test certificates, chemical analysis reports, mechanical testing records and dimensional inspection reports. Third-party inspection such as SGS, BV and customer-appointed inspection agencies can be arranged according to project requirements.
Commonly used alloying elements and their effects are listed in the table given below.
| Alloying Elements | Effect on the Properties |
|---|---|
| Chromium | Increases Resistance to corrosion and oxidation. Increases hardenability and wear resistance. Increases high temperature strength. |
| Nickel | Increases hardenability. Improves toughness. Increases impact strength at low temperatures. |
| Molybdenum | Increases hardenability, high temperature hardness, and wear resistance. Enhances the effects of other alloying elements. Eliminate temper brittleness in steels. Increases high temperature strength. |
| Manganese | Increases hardenability. Combines with sulfur to reduce its adverse effects. |
| Vanadium | Increases hardenability, high temperature hardness, and wear resistance. Improves fatigue resistance. |
| Titanium | Strongest carbide former. Added to stainless steel to prevent precipitation of chromium carbide. |
| Silicon | Removes oxygen in steel making. Improves toughness. Increases hardness ability |
| Boron | Increases hardenability. Produces fine grain size. |
| Aluminum | Forms nitride in nitriding steels. Produces fine grain size in casting. Removes oxygen in steel melting. |
| Cobalt | Increases heat and wear resistance. |
| Tungsten | Increases hardness at elevated temperatures. Refines grain size. |

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
