| High Light | Stress-Relieved Seamless Steel Tube ，ASTM A311 Seamless Steel Tube ，Pipeline Seamless Steel Tube | ||
ASTM A311 is a specification for seamless cold-drawn stress-relieved carbon steel tubes, primarily used in the manufacturing of pipelines. These tubes are designed to withstand high pressures and are often utilized in various industrial applications, including oil and gas, chemical processing, and structural applications.
The ASTM A311 specification outlines the requirements for seamless carbon steel tubes that are cold drawn and stress relieved. The tubes must meet specific mechanical properties and chemical composition standards to ensure their performance in demanding environments.

| Manganese (Mn) | 0.60 - 0.90 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≤ 0.050 |
| Silicon (Si) | 0.10 - 0.40 |
| Chromium (Cr) | ≤ 0.25 |
| Nickel (Ni) | ≤ 0.25 |
| Property | Value |
|---|---|
| Yield Strength (min) | 250 MPa (36,000 psi) |
| Tensile Strength (min) | 450 MPa (65,000 psi) |
| Elongation (min) | 20% |
| Hardness (Brinell) | ≤ 200 HB |
