ASTM B535 NO8330 Seamless Tube
ASTM B535 NO8330 is a specification for seamless tubes made from a nickel-chromium-molybdenum alloy known as NO8330. This alloy is commonly used in high-temperature and corrosive environments due to its excellent resistance to oxidation and corrosion. The seamless tubes produced in accordance with this specification are typically used in industries such as chemical processing, petrochemical, and power generation. The tubes are manufactured to meet specific dimensional and mechanical properties outlined in the ASTM B535 standard.
