Hastelloy Alloy C-22 Round Bar UNS N06022 ASTM B574 W.Nr.2.4602 Nickel Alloy Rod

Hastelloy Alloy C-22 Round Bar is a high-performance nickel-chromium-molybdenum alloy known for its exceptional resistance to both uniform and localized corrosion. This round bar is a solid, cylindrical metal product that is widely used in severe industrial environments where resistance to corrosion is critical.

Description:

• Composition: Hastelloy Alloy C-22 (UNS N06022) consists primarily of nickel, chromium, and molybdenum, with additions of tungsten, iron, and copper. The alloy’s composition is carefully balanced to provide a high level of corrosion resistance across a broad range of chemical environments.

• Physical Properties: The round bar has a density of approximately 0.305 lb/in³ and a melting range between 2460-2520°F (1340-1390°C). It has moderate thermal conductivity and a low magnetic permeability, which makes it suitable for applications where magnetic materials are not desired.

• Mechanical Properties: Hastelloy C-22 round bar offers good mechanical strength with tensile strengths ranging from 90 to 135 ksi (kips per square inch). It also has good yield strength and can withstand moderate temperatures without losing its structural integrity.

• Corrosion Resistance: The alloy’s corrosion resistance is outstanding in both oxidizing and reducing environments. It is particularly resistant to stress corrosion cracking, pitting, crevice corrosion, and corrosion fatigue. It can withstand exposure to a wide range of chemicals, including strong acids, alkalis, and chlorides.

• Dimensions and Tolerances: Hastelloy Alloy C-22 round bars are available in various diameters and lengths, with precise dimensional tolerances to meet the specific requirements of different applications. The bars can be produced to a high degree of straightness and roundness.

• Surface Finish: The round bars typically have a smooth, polished surface finish, which can be further enhanced based on the application’s requirements. The surface finish is important for corrosion resistance and for ease of use in fabricating processes.

• Applications: Hastelloy C-22 round bars are used in a variety of industries, including chemical processing, petrochemical, marine, and pharmaceutical. They are ideal for components such as reactor vessels, heat exchangers, piping, and flanges that are exposed to corrosive media.

• Standards Compliance: The production of Hastelloy Alloy C-22 round bars complies with international standards such as ASTM B446, which specifies the requirements for nickel-chromium-molybdenum alloys in the form of bars and rods.

In summary, Hastelloy Alloy C-22 round bar is a premium material that combines excellent mechanical properties with superior corrosion resistance, making it an ideal choice for demanding applications in harsh chemical and industrial environments. Its ability to withstand a wide range of corrosive conditions makes it a valuable asset in the design and construction of durable, reliable equipment.
