Incoloy 800 is a high-strength, corrosion-resistant alloy used in various industries, from chemical processing, oil and gas to power generation. The alloy is known for its excellent resistance to oxidation and high-temperature strength, making it an ideal choice for high-temperature applications. However, two forms of Incoloy 800 are used: Incoloy 800 round bars and Incoloy 800 pipes. In this blog post, we will explore the differences between Incoloy 800 round bars and Incoloy 800 pipes to help you make an informed decision regarding material selection.
What is Incoloy 800 Round Bars and Incoloy 800?
Incoloy 800 Round Bars and Incoloy 800 are nickel, chromium, and iron alloys that offer many benefits. The primary difference between the two is their shape; Incoloy 800 Round Bars have a cylindrical shape, whereas Incoloy 800 have a rectangular or block shape. They also have slight chemical composition variations, with higher nickel and carbon levels found in the bars than in the blocks. Both provide excellent corrosion resistance against chemicals at elevated temperatures and good formability and weldability. Together they make an ideal material for both high-temperature structural applications such as heat exchangers or petrochemical equipment and demanding industrial applications like nuclear reactors or pollution control systems.
Difference Between Incoloy 800 Round Bars vs Incoloy 800
Application
The main difference between Incoloy 800 round bars and Incoloy 800 is their application. Incoloy 800 round bars are typically used in applications where they will be subject to high temperatures, such as furnace components or heat exchangers. Incoloy 800, on the other hand, is often used in chemical processing equipment where it will not be subject to high temperatures.
Composition
Incoloy 800 round bars and Incoloy 800 are identical in terms of composition. Both contain an austenitic nickel-chromium alloy that offers good resistance to carburization and oxidation. The only difference in composition is the addition of molybdenum in Incoloy 800, which gives it better corrosion resistance than Incoloy800 round bars.
Manufacturing Process
The most significant difference between Incoloy 800 round bars and Incoloy 800 pipes is the manufacturing process involved in each. Incoloy 800 round bars are produced through the hot-rolling process, which involves heating the alloy to high temperatures and then rolling it to the desired size and shape. While Incoloy 800 pipes are either hot or cold drawn, which means pulling the material through a die to get the desired shape and size.
Incoloy 800 Round Bars and Incoloy 800 are made through a combination of hot and cold working. Hot working involves heating alloy beneath its recrystallization temperature, then compression or rolling it into the desired shape, while cold working involves manipulating the material through techniques such as drawing and forging without heat. Besides that, their manufacturing processes differ according to their end purpose: For example, incoloy 800 round bars may need additional machining steps for proper size manipulation before being shipped to customers.
Shape and Size
Incoloy 800 round bars come in various sizes and shapes, including round, hexagonal, and square. They are typically available with a diameter ranging from 5mm to 500mm, with lengths up to 6 meters. Meanwhile, Incoloy 800 pipes are only available in cylindrical tubes, and their sizes are listed based on their outer diameter, wall thickness and length. The size availability of Incoloy 800 round bars makes them a more versatile choice than Incoloy 800 pipes.
In terms of shape and size, Incoloy 800 Round Bars offer greater consistency in dimension tolerance versus the MShape and Size offered by Incoloy 800. With the superior dimensional accuracy associated with round bars, these components are perfect for machining tasks in various industries, including aerospace, chemical processing and food production. Additionally, their improved stability allows for tighter tolerances to be achieved across multiple projects without sacrificing quality or performance.
Mechanical Properties
The mechanical properties of both Incoloy 800 round bars and Incoloy 800 pipes are relatively similar since these two forms of Incoloy 800 alloys are chemically identical. The tensile strength above 500 MPa, yield strength above 200 MPa and elongation above 30 per cent are common characteristics of both forms. The only difference is some minor differences in the microstructure and texture of the alloys.
Pricing and Availability
Finally, another key difference between Incoloy800 round bars and Incoloy800 is cost. Because they are easier to produce, Incoloy800 round bars are typically less expensive than their counterparts. Due to their different manufacturing processes, Incoloy 800 round bars are typically more expensive than Incoloy 800 pipes. The availability of both forms of Incoloy 800 varies depending on the size, shape and quantities required, but generally, Incoloy 800 round bars are readily available in the market compared to Incoloy 800 pipes.
Conclusion:
In summary, both Incoloy 800 round bars and Incoloy 800 pipes offer high-temperature strength and excellent corrosion resistance. However, Incoloy 800 round bars can offer more versatility in terms of size and shape, while Incoloy 800 pipes have a more widespread use in different sectors. Please choose the most suitable one between them, depending on factors like its application, availability and manufacturing cost. Regardless of your choice, you can count on the almighty Incoloy 800 alloy to provide you with the highest quality and strength for your industrial needs.
