ASTM A333 is a specification that covers seamless and welded steel pipe for low-temperature service. The grades included in this specification are designed to provide excellent mechanical properties and impact toughness at low temperatures, making them suitable for various applications in the oil and gas industry, as well as in cryogenic services.
The materials used in the production of ASTM A333 seamless precision steel tubes are carbon and alloy steels. These materials are selected for their ability to withstand low temperatures while maintaining structural integrity.
ASTM A333 is divided into several grades, each with specific requirements regarding chemical composition and mechanical properties. The grades covered under this specification include:
The following table presents the chemical composition requirements for ASTM A333 Grades 1, 3, 4, 6, and 7:
| Grade | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Nickel (Ni) | Chromium (Cr) | Molybdenum (Mo) |
|---|---|---|---|---|---|---|---|
| 1 | ≤ 0.18 | 0.30 - 0.90 | ≤ 0.025 | ≤ 0.025 | - | - | - |
| 3 | ≤ 0.18 | 0.30 - 0.90 | ≤ 0.025 | ≤ 0.025 | 0.40 - 0.70 | - | - |
| 4 | ≤ 0.20 | 0.30 - 0.90 | ≤ 0.025 | ≤ 0.025 | 0.40 - 0.70 | 0.40 - 0.60 | - |
| 6 | ≤ 0.20 | 0.30 - 0.90 | ≤ 0.025 | ≤ 0.025 | 0.40 - 0.70 | 0.40 - 0.60 | 0.15 - 0.25 |
| 7 | ≤ 0.20 | 0.30 - 0.90 | ≤ 0.025 | ≤ 0.025 | 0.40 - 0.70 | 0.40 - 0.60 | 0.15 - 0.25 |
The mechanical properties of ASTM A333 seamless precision steel tubes are crucial for their performance in low-temperature environments. The following table summarizes the mechanical properties for each grade:
