ASTM B407 UNS N08810 Alloy Pressure Vessel Pipe
ASTM B407 UNS N08810 Alloy Pressure Vessel Pipe
ASTM B407 UNS N08810 refers to seamless nickel-iron-chromium alloy tubing, specifically Incoloy 800H, which is widely used in high-temperature and corrosive pressure vessels due to its excellent strength, corrosion resistance, and high-temperature creep/rupture strength. It is suitable for high-temperature environments in the chemical processing, power generation, and petrochemical industries, and offers resistance to oxidation, sulfidation, and carburization.
What is ASTM B407 material?
ASTM B407 is a commonly used standard for seamless nickel-iron-chromium alloy pipe. It specifies requirements for chemical composition, mechanical properties, and other properties. Incoloy 800, 800H, and 800HT are commonly used grades in this standard.
