Hastelloy C-276 Equivalent ASTM Grade
Hastelloy C-276 Equivalent ASTM Grade
Hastelloy C-276 (UNS N10276) does not have a single ASTM "equivalent" standard. Instead, there are multiple ASTM specifications depending on the product form, such as: B622/B619/B626 for pipes/fittings, B575 for plates/sheets, B574 for bars/rods, and B564 for forgings. All these standards cover the same corrosion-resistant nickel-chromium-molybdenum alloy. These standards define the material composition (UNS N10276) and properties for various applications, therefore they are interchangeable.
What is the ASTM equivalent material for Hastelloy C276 seamless pipe?
Hastelloy C276 Round Pipe Equivalent Material
Hastelloy C276 pipe is a corrosion-resistant alloy, and its equivalent materials include UNS N10276, WNR 2.4819, and ASTM B622. These materials have similar corrosion resistance and high-temperature resistance.
Hastelloy C276 is a high-performance nickel-based alloy primarily composed of nickel, molybdenum, chromium, iron, and tungsten. Nickel is the main element, imparting excellent toughness and ductility. The addition of chromium and molybdenum significantly improves the alloy's corrosion resistance, enabling it to operate stably for extended periods in harsh corrosive environments. Furthermore, Hastelloy C276 also contains trace amounts of iron, tungsten, and cobalt to further optimize its properties.
