Hastelloy C4 Manufacturer
Hastelloy C4 also known as UNS N06455 is a nickel-based alloy. It contains a high percentage of nickel, chromium, and molybdenum. Also, the alloy has smaller amounts of iron, tungsten, and cobalt. With a combination of elements, N06455 exhibits high-temperature resistance.
Tuolian Hastelloy C4 is well-suited to a range of industrial applications where other materials may fail. Some of its common applications include chemical processing, nuclear fuel processing, wastewater treatment, marine industries, power generation plants, pharmaceutical and food processing equipment, sour gas wells, pulp and paper production, etc.
This alloy can withstand oxidation and scaling at temperatures up to 1900°F (1038°C). In corrosive environments, N06455 can resist harsh chemicals like chlorine-containing media, salt water, solvents, strong acids, chlorides, and more.
These are some of the main ASTM specifications that apply to Hastelloy C4: ASTM B574, ASTM B619, ASTM B575, ASTM B622, and ASTM B626.
At Tuolian, you can find Hastelloy C4 in various forms – strip, sheet, plates, pipe, fine wire, flat, round, and square. It is also available in a range of sizes, diameters, and wall thicknesses; both in standard and customized specifications.

- Physical and Mechanical Properties
Machining – Hastelloy C4 has a low machinability rating. Care must be taken to prevent tool wear and premature failure.
Forming – It can be formed using standard techniques such as rolling, bending, and forging.
Welding – This alloy can be welded using a variety of techniques, including TIG, MIG, and SAW welding.
Heat Treatment – They are typically annealed at temperatures ranging from 1038°C to 1149°C (1900°F to 2100°F) to relieve stress and restore ductility.
Cutting – Hastelloy C4 can be cut using conventional cutting tools, but the use of carbide or high-speed steel tools is recommended for best results. Waterjet cutting is another option.
