A106 Material-Seamless Pipe
A106 material is mainly used for seamless pipes of high temperature and high pressure. There are ASTM and ASME standards. The requirements between the two are similar. It is often used in construction and oil pipelines. There are three grades under this standard, Grade A, Grade B, and Grade C. From Grade A to Grade C, the strength gradually increases, the carbon content gradually increases, but the plasticity and toughness gradually decrease. The specification we commonly use is Grade B material.
Common A106 Grade
A106 Grade A Pipe
It is a seamless pipe with carbon content less than 0.25% and manganese content less than 0.93%, with minimum tensile strength.
A106 Grade B Pipe
It is a seamless pipe with carbon content less than 0.30% and manganese content less than 1,06%, with moderate tensile strength.
A106 Grade C Pipe
It is a seamless pipe with carbon content less than 0.35% and manganese content less than 1,06%, with high tensile strength.

Understanding A106 Grade B
A106 Grade B steel pipe is your most balanced choice, and it is a product we often use. BalingSteel can provide you with A106 Grade B steel pipe by hot rolling and cold drawing. Hot rolling is mainly suitable for large-diameter steel pipes with thicker walls, while cold drawing is mainly suitable for small-diameter steel pipes with high uniformity of wall thickness. Welcome to contact BalingSteel for the latest price quote.
ASTM A106 Grade B is a medium carbon seamless carbon steel pipe specification, mainly used for high temperature and high pressure projects with excellent weldability, formability, strength and good ductility.
A106 is an American Society for Testing and Materials (ASTM) designation for seamless carbon steel pipe for high temperature applications.
From A, B, C grades, the carbon content gradually increases, the ductility gradually decreases, and the tensile strength gradually increases.
- A106 B grade steel pipe is a professional high-temperature pipe that requires systematic high-temperature testing and certification. It is a seamless pipe standard.
- API 5L steel pipe is a petroleum and natural gas pipeline standard. It can be a seamless pipe or a welded pipe standard.
- ASTM A53 B grade steel pipe is a structural pipe. It can be a seamless pipe (S type) or a welded pipe (E type or F type).
- Tensile strength: Minimum 60,000 psi (415 MPa)
- Yield strength: Minimum 35,000 psi (240 MPa)
- Hardness: Typically 80-95 HRB (Rockwell B).
- Maximum Temperature Rating: A106 Grade B pipe is typically rated up to approximately 750°F (400°C)
The A106 B-grade pipes provided by BalingSteel are mainly used for steam and boiler piping systems, power plant construction, refinery processing production lines, petrochemical plant pipelines, high-pressure fluid transportation and other high-temperature environment pipes.
- Wall thickness tolerance: Typically ±10% of nominal wall thickness,
- Pressure rating:The A106 specification does not specify the pressure rating, so we make a judgment based on the actual pipe size and design, and calculate it according to the formula in ASME B31.1, B31.3 or ASME Boiler and Pressure Vessel Code
Please read the specification sheet for detailed specifications:
| API 5L GRB | ASTM A53 GRB | S235JR | ASTM A36 | P235GH | STPT370 | Grade 20 | St 35.8 | St 45.8 | IS 1239 | CSA B51 |
If the design requirements do not specify seamless pipes or welded steel pipes, you can choose between the two. If the regulations require the selection of welded pipes, then we need to use ASTM A53.
Yes, A106 Grade B is definitively classified as carbon steel. Its carbon content specification is maximum 0.30% by weight.
