ASME SB163 UNS N04400 Nickel Alloy Seamless Bright Face Pipe
ASME SB163 UNS N04400 Nickel Alloy Seamless Bright Face Pipe
ASME SB163 UNS N04400 nickel alloy seamless mirror finish tubing is a Monel 400 nickel-copper alloy tubing manufactured in accordance with ASME SB163 standards. It is renowned for its high strength, excellent corrosion resistance in various media, including seawater and acidic environments, and its ability to withstand a wide range of temperatures. "Seamless" refers to the absence of weld seams when the tubing is formed, and "mirror finish" refers to the highly polished surface. These properties make it suitable for demanding applications such as chemical processing, marine environments, oil and gas, and heat exchangers.
What is the maximum operating temperature of Monel 400?
Hot working temperatures range from 1700°F to 2150°F. Optimum working temperature is approximately 2000°F. By properly controlling the amount of hot working and/or cold working and selecting the appropriate heat treatment method, a wide range of mechanical properties can be achieved in the finished product.

Standards and Surface Treatments
ASME SB-163: This standard specifies requirements for seamless nickel and nickel alloy condenser and heat exchanger tubes.
Mirror Polish: This polished surface finish is typically used in applications requiring a high-quality, bright, and clean appearance.
Testing and Applications
Testing: This specification requires testing such as chemical analysis, tensile testing, Rockwell hardness testing, and grain size testing.
Applications: Due to its properties, it is used in heat exchangers, marine applications, oil and gas production, and chemical processing.
Gnee Steel specializes in the production of various nickel-based alloys. Gnee Steel's product packaging includes steel strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during sea transportation, and then secured with steel strapping. Wooden boxes/crates: Pipes are typically packaged in wooden boxes or crates to protect them during transportation, especially those that are longer or have larger diameters. Seaworthy export packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin packaging: This prevents rain, seawater, and other external factors from penetrating the export wooden crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in aerospace, chemical, power, automotive, and nuclear energy industries, and we can provide customized alloy material solutions based on customer needs.
