- Hastelloy Tubes
Midland Alloys is a trusted ASTM B622 Hastelloy Gas Tube Ar 15 supplier, providing high-performance tubing worldwide. Hastelloy Tube is known for high resistance to strong oxidizers, reducing agents, and harsh chemicals. Available in grades hastelloy C22 and hastelloy C276 which is composed of nickel, molybdenum, chromium, tungsten, iron, cobalt, manganese, silicon, phosphorus, sulfur, vanadium, and carbon. These tubes are produced in a variety of forms such as hastelloy seamless tube under ASTM B622/ASME SB622 specifications and hastelloy alloy welded tube under ASTM B619/ASTM B626. Size range from 1/2″ to 48″ with wall thicknesses range from 0.5mm to 20mm. Shapes include round, square, rectangular, coiled, U-shape, hydraulic, and pancake. Our Hastelloy C276 round tube is used for its mechanical strength and high resistance in aggressive environments. Precision melting, extrusion, or tube rolling are used during the manufacturing process, followed by heat treatment, cold working, and finishing to ensure correct dimensions and consistent metallurgical qualities. With extensive testing and stringent quality controls, we ensure that every tube meets international standards and project requirements.
Difference Between Hastelloy Tube vs Inconel Tube
Both hastelloy and inconel tubes are nickel-based alloys, however they perform distinct functions. Hastelloy tubes are selected for their resistance to strong oxidizers, reducing agents, and chemically rich environments such as acids and chlorides. Inconel tube is engineered to withstand high temperatures and oxidation, making it perfect for gas turbines, exhaust systems, and aerospace components. Hastelloy tube is used in chemical processing plants and marine environments, while Inconel tube finds its strength in high-temperature applications. The choice depends on whether the priority is chemical resistance or thermal stability.
Benefits of ASME SB622 Hastelloy Tubing
Hastelloy Tubing is built for reliability in harsh and corrosive environments. It offers durability, strength, and performance that make it a trusted choice across industries. Here are the top benefits:
- Provide excellent resistance to corrosion in aggressive chemicals, acids, and seawater environments.
- Prevents localized damage such as pitting and stress corrosion cracking in chloride-rich conditions.
- These tubes maintain strength and stability even when exposed to high operating temperatures.
- ASME SB622 Hastelloy Tubing perform effectively in both oxidizing and reducing atmospheres without losing reliability.
- Provide long service life, reducing downtime and replacement costs in demanding applications.
- These tubes handle high pressure with superior mechanical toughness and structural integrity.
- Ensure safe, consistent performance in industries where reliability is must.

Uses of Hastelloy Tubes
Hastelloy tubing is utilized in a variety of industries for specialized applications. In chemical processing, hastelloy square tube is used for heat exchangers, scrubbers, and evaporators. Hastelloy boiler tubes are used in power plants to generate steam at extreme pressures and temperatures. The oil and gas sector use these tubes in downhole and subsea equipment that is exposed to seawater and sour gas. The pharmaceutical and food sectors rely on hastelloy rectangular tubes in clean, sterile conditions where corrosion resistance is critical. In marine applications, square and rectangular tubes are utilized for structural supports and saltwater-exposed fluid handling systems. These tubes are utilized in the aerospace and defense industries for fuel systems, hydraulic lines, and engine sections that are subjected to extreme stress and corrosion.
