ASTM B407 UNS N08810 Nickel alloy steel welded pipe for power generation
ASTM B407 UNS N08810 Nickel alloy steel welded pipe for power generation
ASTM B407 UNS N08810 welded steel pipes are high-performance nickel alloy steel pipes suitable for power generation due to their excellent strength, corrosion resistance, and high-temperature stability. They can be used in applications such as process piping and heat exchangers in high-temperature environments. This alloy has good oxidation and carburization resistance and maintains good ductility at high temperatures for extended periods.
What is ASTM B 407 material?
ASTM B407 is a commonly used standard for seamless nickel-iron-chromium alloy tubing. It specifies requirements for chemical composition, mechanical properties, and other aspects. Incoloy 800, 800H, and 800HT are commonly used grades in this standard.
ASTM B407 UNS N08810 is a high-performance nickel-iron-chromium alloy, also known as Incoloy 800HT. It is designed for applications requiring excellent strength and corrosion resistance at high temperatures. This alloy is commonly used in environments requiring resistance to oxidation, carburization, and high-temperature creep.
