A333 Seamless & Welded Steel Pipe
ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11.
Product Parameters
| A333 Seamless & Welded Steel Pipe Description |
| The main components of A333 seamless steel pipe include iron, carbon, chromium, nickel, manganese and other elements. Chromium has excellent corrosion resistance, while the addition of nickel further enhances the corrosion resistance and toughness of the material. A333 seamless steel pipe has high strength and hardness, as well as good plasticity and toughness. These excellent mechanical properties make A333 seamless steel pipe an ideal choice in many high-strength, high-corrosion-resistant application scenarios. A333 seamless steel pipe is commonly used to transport oil and natural gas with high temperature and high pressure owing to the excellent sealing and corrosion resistance. |
