Cold Drawn Seamless Steel Pipe ASTM A333 Grade 6 is designed for low temperature service applications. It is commonly used in industries such as oil and gas, petrochemical, and power generation, where reliable performance at low temperatures is crucial. This article provides detailed information about the material, specification, chemical composition, mechanical properties, steel grade, and application of ASTM A333 Grade 6 seamless steel pipes.
The material used for manufacturing ASTM A333 Grade 6 seamless steel pipes is fine-grain, low-alloy steel. This type of steel exhibits excellent toughness and impact resistance, making it suitable for low-temperature applications. It is specifically designed to withstand harsh operating conditions and maintain its integrity at temperatures as low as -50°F (-45°C).
ASTM A333 Grade 6 specifies the requirements for seamless and welded steel pipe for low-temperature service. The pipes are produced using a seamless or fusion welding process, with the final product being either hot-finished or cold-drawn. The standard covers nominal (average) wall thicknesses ranging from 1/8 inch to 3 inches (3.2mm to 76mm).
The chemical composition of ASTM A333 Grade 6 seamless steel pipes is as follows:
| Element | Composition, % |
|---|---|
| Carbon (C) | 0.30 max |
| Manganese (Mn) | 0.29 - 1.06 |
| Phosphorus (P) | 0.025 max |
| Sulfur (S) | 0.025 max |
| Silicon (Si) | 0.10 min |
| Nickel (Ni) | 3.18 - 3.82 |
| Chromium (Cr) | 0.44 - 0.65 |
| Copper (Cu) | 0.40 max |
The mechanical properties of ASTM A333 Grade 6 seamless steel pipes are as follows:
| Property | Value |
|---|---|
| Tensile Strength | 60,000 - 70,000 psi |
| Yield Strength | 35,000 - 45,000 psi |
| Elongation | 16% min |
| Impact Toughness | Charpy V-notch: 15 ft-lb (20 J) min at -50°F (-45°C) |
ASTM A333 Grade 6 is a steel grade specifically developed for low-temperature service. It is known for its exceptional toughness, ductility, and impact resistance at sub-zero temperatures. The steel grade is widely used in various industries where reliable performance at low temperatures is required.
ASTM A333 Grade 6 seamless steel pipes find extensive application in industries involving low-temperature environments. Some of the common applications include:
