Hastelloy is a family of nickel-based alloys that are known for their excellent corrosion resistance in a variety of harsh environments. Hastelloy alloys are used in a wide range of industries, including chemical processing, aerospace, and marine engineering. Here is a brief description of Hastelloy products with grades
- Hastelloy C276: Hastelloy C276 is a nickel-molybdenum-chromium alloy that offers excellent corrosion resistance in a wide range of environments, including oxidizing and reducing environments. It is often used in chemical processing, pulp and paper production, and other industrial applications.
- Hastelloy B-2: Hastelloy B-2 is a nickel-molybdenum alloy that is highly resistant to hydrochloric acid, sulfuric acid, and other strong acids. It is often used in chemical processing, pharmaceuticals, and other applications where strong acids are present.
- Hastelloy X: Hastelloy X is a nickel-chromium-iron-molybdenum alloy that offers excellent oxidation resistance at high temperatures. It is often used in gas turbine engines, industrial furnaces, and other high-temperature applications.
- Hastelloy C-22: Hastelloy C-22 is a nickel-chromium-molybdenum-tungsten alloy that offers excellent resistance to oxidizing and reducing environments. It is often used in chemical processing, waste treatment, and other applications where corrosion resistance is critical.
- Hastelloy G-30: Hastelloy G-30 is a nickel-chromium-molybdenum alloy that offers excellent resistance to phosphoric acid and other oxidizing and reducing acids. It is often used in chemical processing, pulp and paper production, and other industrial applications.
Hastelloy products with these grades include pipes, tubes, flanges, fasteners, fittings, and round bars.
