ASTM B668 UNS N08028 Seamless Tubing is a high-performance alloy tubing with excellent corrosion resistance and mechanical properties. Here’s a detailed breakdown of the seamless tube: 1. Overview of the standard Standard number: ASTM B668 Second, the main requirements Alloy composition: UNS N08028 seamless tubing is mainly composed of elements such as nickel (Ni), chromium (Cr), molybdenum (Mo) and copper (Cu). The specific chemical composition is usually Ni = 31%, Cr = 27%, Cu = 1.0%, Mo = 3.5%, and it also contains small amounts of carbon (C), manganese (Mn), phosphorus (P), sulfur (S) and silicon (Si), as well as iron (Fe) as a retention. Characteristic: Due to its high nickel and chromium content, as well as the addition of alloying elements such as molybdenum and copper, UNS N08028 seamless tubing excels in a wide range of corrosive environments, especially in highly reducing, oxidizing, oxidation-reduction composites, and halogen-containing media, and is resistant to both general and localized corrosion. The alloy has an austenitic structure, so it has excellent strength, plasticity, and toughness. Its welding performance is also very good, making it easy to process and install. Third, the field of application UNS N08028 seamless tubing is widely used in a variety of fields due to its excellent performance, including but not limited to: Chemical: used to manufacture all kinds of corrosion-resistant chemical equipment and pipelines. Flue gas desulfurization: As a key component in the flue gas desulfurization system, it resists harsh corrosive environments. Seawater heat exchanger: It is used as a material for seawater heat exchanger in marine engineering to resist the corrosion of seawater. Oil and gas industry: used in oil and gas well pipelines and oil and gas processing equipment. Nuclear industry: It also has applications in nuclear fuel reprocessing and other nuclear-related equipment. 4. Precautions When purchasing UNS N08028 seamless pipes, it is recommended to pay attention to the following points: Choose regular suppliers: ensure that suppliers have the corresponding qualifications and reputation, and can provide products that meet the standards. Check the product identification: check whether the identification on the product is clear and accurate, including the standard number, material name, specification and size and other information. Inspection of product quality: If conditions permit, suppliers can be required to provide product inspection reports or conduct sampling inspections to ensure that product quality meets the standard requirements. In summary, ASTM B668 UNS N08028 seamless pipe is a high-performance alloy pipe with a wide range of application prospects and market demand. When selecting and using, its characteristics and requirements should be fully understood to ensure that the quality and performance of the product meet the actual needs.Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
