ASTM A333 is a standard developed by the American Society for Testing and Materials. The full name of ASTM A333 is: ASTM A333/A333M – Standard Specification for Seamless and Welded Steel Pipe for Low-Temperature Service and Other Applications with Required Notch Toughness. In summary, A333 is specially developed for low-temperature applications.
ASTM A333 Standard
A333 Standard Pipe Process

Steel Grades Chemical Composition Chart
The ASTM A333 standard covers many steel grades: Grade 1, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10, and Grade 11. Different steel grades have different chemical compositions and heat treatment types. Grades 1, 3, 4, 6, 9, and 11 are specifically certified for both ERW and SMLS processes, while Grades 7, 8, and 10 can only be processed using SMLS.

ASTM A333 Mechanical Properties
The ASTM A333 standard primarily specifies tensile strength and yield strength. The minimum tensile strength and yield strength vary for different steel grades. You can select the most suitable steel grade for your application based on the data below.
Application Areas
- Liquefied Natural Gas (LNG) Industry Chain
LNG is stored at approximately -162°C. This ultra-low temperature environment is ideal for ASTM A333 pipes, which are used in transportation, cold energy utilization, and BOG processing. - Petrochemical Industry
Many chemical processes require ultra-low temperatures. A333 pipes are used in ethylene plants with a boiling point of -104°C, propylene plants with a boiling point of -47.7°C, and for the transportation of liquid nitrogen and butane. - Industrial Refrigeration
For example, chemical cold storage, food processing freezing lines, and artificial snowmaking systems require low-temperature environments.
