ASTM A334 is a specification that covers several grades of alloy-steel tubes designed for low-temperature service. These tubes are primarily used in applications where the material must maintain its strength and toughness at low temperatures, making them suitable for various industries, including oil and gas, petrochemical, and power generation.
The ASTM A334 specification includes several grades, each with specific chemical and mechanical properties. The grades covered under this specification are:
The following table presents the typical chemical composition for each grade of ASTM A334:
| Grade | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | Molybdenum (Mo) | Nickel (Ni) |
|---|---|---|---|---|---|---|---|
| 1 | 0.20 max | 0.40 - 0.90 | 0.035 max | 0.025 max | 0.40 - 0.65 | - | - |
| 3 | 0.20 max | 0.40 - 0.90 | 0.035 max | 0.025 max | 0.40 - 0.65 | 0.15 - 0.25 | - |
| 6 | 0.30 max | 0.40 - 0.90 | 0.035 max | 0.025 max | 0.40 - 0.65 | 0.15 - 0.25 | 0.40 - 0.70 |
| 7 | 0.30 max | 0.40 - 0.90 | 0.035 max | 0.025 max | 0.40 - 0.65 | 0.15 - 0.25 | 0.40 - 0.70 |
| 8 | 0.30 max | 0.40 - 0.90 | 0.035 max | 0.025 max | 0.40 - 0.65 | 0.15 - 0.25 | 0.40 - 0.70 |
The following table summarizes the mechanical properties for each grade of ASTM A334:
| Grade | Yield Strength (ksi) | Tensile Strength (ksi) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| 1 | 30 | 60 - 75 | 30 | 120 max |
| 3 | 30 | 60 - 75 | 30 | 120 max |
| 6 | 35 | 70 - 85 | 30 | 130 max |
| 7 | 35 | 70 - 85 | 30 | 130 max |
| 8 | 35 | 70 - 85 | 30 | 130 max |
The steel grades under ASTM A334 are specifically designed for low-temperature applications, ensuring that they can withstand the rigors of harsh environments while maintaining structural integrity.
ASTM A334 alloy-steel tubes are widely used in:
While ASTM A334 grades are specifically tailored for low-temperature service, some alternative grades that may be considered include:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
