ASTM B709 Iron-Nickel-Chromium-Molybdenum Alloy (UNS N08028) Sheets, sheets, and strips are a special alloy material that is widely used in a variety of applications that require high corrosion resistance and high-temperature strength. Here are the detailed answers to the alloy plates, sheets and strips: 1. Overview of the standard Standard number: ASTM B709 Second, the main requirements Material Properties: Alloy N08028 is a high-alloy austenitic stainless steel designed for use in highly aggressive and corrosive environments. Its chemical composition includes elements such as iron, nickel, chromium, molybdenum, etc., and the combination of these elements gives the alloy excellent corrosion resistance and high-temperature strength. The alloy has a very low carbon content, so it has good resistance to intergranular corrosion, the corrosion resistance does not decrease after multiple welds, and the resistance to pitting and crevice corrosion is also good. Processability: The process properties of this alloy are similar to those of general austenitic stainless steels, but attention needs to be paid to the work hardenability of the material. Machining is carried out after solution treatment and uses low surface cutting speeds and refeed volumes. Heat treatment: The solution treatment temperature range is 1050-1150C, and the holding time depends on the maximum cross-sectional area of the workpiece, and the cooling method is preferably water-cooled. The thermoforming temperature range is 950-1150C, and thermoforming operations in the sensitized temperature range of 500-720C should be avoided Third, the field of application N08028 alloy plates, sheets and strips are widely used in the following fields due to their excellent corrosion resistance and high temperature strength: Chemical processing equipment: equipment used to manufacture chemical media resistant to acids, alkalis, etc., such as evaporators, reactors, etc. Pollution control equipment: used in flue gas desulfurization systems, wastewater treatment and other fields to manufacture corrosion-resistant pipes, valves and other components. Oil and gas industry: used in the manufacture of oil well casing, pipes and other components, especially in the environment containing hydrogen sulfide (H2S) and chloride, with good resistance to stress corrosion cracking. Wet phosphoric acid production: In the production process of wet phosphoric acid, it is used to manufacture heat exchangers, storage tanks and other equipment to cope with strong corrosive phosphoric acid media. IV. Conclusions In summary, ASTM B709 Fenic-Chromium-Molybdenum Alloy (UNS N08028) Sheets, Sheets, and Strips is a special alloy material with excellent corrosion resistance and high-temperature strength that plays an important role in several industrial sectors..Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
