ASTM B407 UNS N08810 / Incoloy 800H / DIN 1.4958 Seamless Nickel Alloy Tube

ASTM B407 Incoloy 800H Seamless Tubing , UNS N08810 / IN 1.4958 Nickel Alloy Tube

ASTM B407 is a specification that establishes the standards for seamless tubes made from high-temperature nickel alloy materials, particularly the Inconel 800/800H/800HT alloys. The 800H alloy, comprised primarily of nickel, chromium, and iron, is designed to perform well in high-stress environments where components may be subjected to extreme heat and corrosive elements. The seamless construction of these tubes offers superior integrity and reliability, reducing the likelihood of failure in critical applications. Seamless tubes are manufactured without the presence of a welded seam, which can be a point of weakness in welded constructions.

ASTM B407 Incoloy 800H Seamless Nickel Alloy Tube Mechanical Properties

There are several compelling reasons to consider using ASTM B407 800H seamless tubes made from Inconel 800H alloy:

1. High-Temperature Strength: Inconel 800H is engineered to maintain its mechanical properties even at elevated temperatures, making it ideal for applications in power generation and furnace components.

2. Corrosion Resistance: The alloy exhibits excellent resistance to oxidation and carburization, which are common issues in high-temperature environments. This helps prolong the life of components and reduce maintenance costs.

3. Seamless Construction: The absence of a weld seam improves the overall integrity of the tubes, minimizing the risk of failure under pressure or mechanical stress. This makes them more reliable for critical applications.

4. Versatility: ASTM B407 800H tubes are applicable in various industries, including petrochemical, aerospace, and nuclear, allowing for broad usage across different sectors.

5. Fabrication and Welding: The alloy can be readily fabricated and welded, facilitating the manufacturing of complex components without compromising performance.

6. Compliance and Quality Assurance: Using materials that meet ASTM B407 standards ensures adherence to industry regulations and quality assurance, enhancing safety in critical applications.
