ASTM A 333 Gr 6 Low Temperature Carbon Steel Pipe & Tubes

ASTM A333 Grade 6 Pipe is a carbon steel pipe that comes under ASTM, ASME, and API standards. There are grades 1 through 11 in the pipe series and the sizes range from ½ inches to 36 inches. The wall thickness of the pipes ranges from 3mm to 12mm and the ASME SA 333 GR 6 Seamless Pipe comes under different schedules such as sch40, sch80, and up to XXS including all schedules.

The cold drawn and cold rolled pipe types are available. There are seamless, welded, ERW, and fabricated pipes. The seamless pipes are drawn from a single billet of the material whereas the ASTM A333 Grade 6 Welded Pipe Specification mandates it be welded from a strip or sheet of the same material grade. The form of the pipes can vary, such as round or hydraulic, in most cases.

Amardeep Steel is a leading manufacturer and supplier of these A333 Grade 6 Pipe types in varying wall thicknesses as well. The wall thicknesses range from 3mm to 12mm in different schedules. ASTM A333 Grade 6 Pipe is a carbon steel material intended for low-temperature applications. The standards and grades vary according to the application requirements. ASTM A333 Pipe ranges in diameter from ½ inches to 36 inches. The schedules range from sch40 through XXS and all schedules are according to the customer requirements. There are cold-drawn and cold-rolled A333 Seamless Pipe types. ASTM A333 Pipe can come in seamless, ERW, welded, fabricated, and CDW types. The forms of the pipes vary from round to hydraulic. The Ltcs ASTM A333 Gr 6 comes in different lengths from 3m to 18m depending on the custom requirements of the applications. The pipe ends also differ in terms of different operation types. The SA333 Pipe can have a plain end, beveled end, or threaded end type.

Since these are low-carbon materials, A333 Gr 6 Material need to be preheated before welding. The preheating allows the ASTM A333 Pipe to have enough ductility to not develop welding cracks. The applications of the pipes are seen primarily in the oil and gas industry, petroleum industry, and oil and gas transmission lines. ASTM A333 pipes are also found in structural applications such as construction, alongside standard ASTM A53 pipes

Our A333 Gr 6 Material is of high standard and it undergoes all the testing necessary to make sure of the quality. ASTM A333 pipes can come in different diameters and wall thicknesses. The wall thickness can range from 3mm to 12mm and there are different schedules to cope with different pressure requirements. The schedules of the SA333 Pipe range from 40 to SCH XXS and all schedules. We can produce any custom-made ASTM A333 Pipe components for our customers. Our pricing is also competitive to the market.

A333 Gr 6 Chemical Composition

This chemistry is what gives ASTM A333 Grade 6 its low-temperature character. With a maximum 0.30% carbon and balanced 0.29–1.06% manganese, the A333 Gr 6 Material achieves fine-grain toughness without sacrificing weldability. Tight phosphorus and sulphur limits keep the Low Temperature Carbon Steel Pipe clean and ductile, supporting consistent impact performance in cryogenic and sub-zero service.

A333 Gr 6 Mechanical Properties

These mechanical values define the dependable strength of ASTM A333 Grade 6 Pipe. A minimum yield of 240 MPa, tensile strength of 415 MPa, and 30% elongation give A333 Gr 6 Material the elasticity and impact resistance demanded in low-temperature pressure systems. The same property set applies to SA333 Gr 6 supplied to ASME, ensuring predictable design behaviour across applications.

FAQs

1. What is ASTM A333 Grade 6?

ASTM A333 Grade 6 is a low-temperature carbon steel pipe specification for seamless and welded pipe used in cold-service applications. It belongs to the ASTM A333 standard (Grades 1–11) and is defined by a controlled low-carbon chemistry plus mandatory impact-toughness testing, ensuring the pipe resists brittle fracture at sub-zero temperatures in pressure and cryogenic systems.

2. What is A333 Gr 6 material made of?

A333 Gr 6 Material is a low-carbon steel with a maximum 0.30% carbon and 0.29–1.06% manganese, plus tightly controlled phosphorus and sulphur. This balanced composition delivers fine-grain toughness, good weldability, and ductility. The chemistry is what allows ASTM A333 Grade 6 Pipe to perform reliably in low-temperature pressure and transmission service.

3. What is the temperature range of ASTM A333 Grade 6 pipe?

ASTM A333 Grade 6 pipe is designed for low-temperature service, typically rated for use down to about −45 °C (−50 °F). Its verified Charpy V-notch impact toughness makes it the preferred Low Temperature Carbon Steel Pipe for cryogenic, refrigeration, LNG/LPG, and cold-climate applications where standard carbon steel would become brittle.

4. Is SA333 Gr 6 the same as ASTM A333 Grade 6?

Yes. SA333 Gr 6 is the ASME designation for the identical material covered by ASTM A333 Grade 6. The "SA" prefix indicates the grade is supplied under ASME Boiler and Pressure Vessel Code requirements. Chemistry, mechanical properties, and impact testing are the same, so SA333 Gr 6 and A333 Gr 6 are interchangeable in specification.

5. What is the A333 Gr 6 equivalent grade?

The main A333 Gr 6 equivalent is EN 10216-4 P265NL for seamless pipe. SA333 Gr 6 is the ASME pressure-code equivalent. Referencing these equivalents helps buyers cross-check international standards and source ASTM A333 Grade 6 Pipe globally while maintaining the same low-temperature toughness and pressure ratings.

6. What is the difference between ASTM A333 and ASTM A106?

ASTM A106 Grade B is a high-temperature seamless carbon steel pipe, whereas ASTM A333 Grade 6 is built for low-temperature service with mandatory impact testing. A106 is produced seamless only; A333 Gr 6 is available seamless or welded. For sub-zero, cryogenic, or cold-climate piping, A333 Gr 6 is the correct choice over A106.

7. What sizes and schedules are available for ASTM A333 Grade 6 pipe?

ASTM A333 Grade 6 Pipe is offered from ½″ NB up to 36″ NB (large-diameter SAW to 100″ NB), in schedules from SCH 5, 10, 20, 30, 40, STD, 60, 80, 120, 140, 160, XS, and XXS. Wall thickness typically ranges from 3 mm to 12 mm, with custom dimensions and lengths up to 16,000 mm available.

8. What testing and certification come with A333 Gr 6 pipe?

Each ASTM A333 Grade 6 order is supplied with EN 10204 3.1 mill test certificates and full material traceability. Additional testing such as NACE MR0175, HIC, SSC, H2 service, and third-party inspection is available on request, ensuring your A333 Gr 6 Material meets project, audit, and code requirements.

9. What is the low temperature carbon steel ASTM code?

ASTM A333 is the primary ASTM code for low-temperature carbon steel pipe, with Grade 6 being the most widely used grade. The ASME equivalent is SA333. For low-temperature seamless tubes, ASTM A334 is also referenced. ASTM A333 Grade 6 remains the industry-standard Low Temperature Carbon Steel Pipe specification.

10. Where is ASTM A333 Grade 6 pipe used?

ASTM A333 Grade 6 Pipe is used in cryogenic and refrigeration systems, LNG/LPG handling, oil & gas transmission lines, petrochemical plants, pressure piping, and cold-region structural construction. Because A333 Gr 6 Material combines toughness, weldability, and pressure capability, it suits both fluid-transport and load-bearing applications worldwide.
