Hastelloy C22 Round Bars

Round Bars are long-cylindrical non-hollow rods useful in numerous domestic and industrial applications. We can cut these round bars to produce machinery parts and automobile components like grills, fasteners, flanges, valves, etc.

Hastelloy C22 is a nickel-chromium-molybdenum superalloy. It exhibits good mechanical and chemical properties, which provides excellent resistance to oxidizing solutions. Also, its nickel content is sufficient to protect the surfaces against chloride-ion stress corrosion cracking.

Hastelloy C22 enhances the strength, stability, and durability of the round bars in extreme environments. It also contains tungsten (3% approx.) which exhibits low thermal expansion that provides additional strength and endurance in high-temperature areas.

Mangalam Metal Corporation is one of the globally leading distributors and suppliers of Hastelloy C22 Round Bars across the globe. We use high-quality raw materials to manufacture round bars to meet national and international standards.


Round bars are essential in various machinery applications. The followings are some basic applications of Hastelloy C22 Round Bars:

  • Producing the machinery and piping fittings like nuts & bolts, screws, couplings, reducers, etc.
  • Constructing the railway tracks and fencings in the nearby areas.
  • Assembling the machinery equipment.

Round Bars are available in various shapes and sizes. However, depending upon the scope of work and use, they have different attributes and applications.

For instance, round bars are round, non-hollow cylindrical-shaped rods. Technically, the diameter of the round bar ranges from 0.25 inches to 24 inches, and the length varies from 50 mm to 6000 mm. They are available in various grades, including nickel alloys, stainless steel, titanium, brass, and plastics.

On the other hand, Shafts, also known as Turned Ground or Polished Shafting, are round circular rods that rotate faster in high-accuracy applications like laboratory equipment, high-speed motor shafts, or pump shafts. One needs to be sure that these shafts are precisely straight to prevent malfunctioning of the machinery against higher pressure and stress.

  • Hastelloy C22 contains higher tungsten and ferrous content, enhancing the toughness of the round bars during the fabrication process.
  • Hastelloy C22 exhibits oxidation and carbonization resistance in high-temperature areas. During the heating process, it eliminates the risk of losing carbon components and maintains the strength and integrity of the round bars.
  • Hastelloy C22 coating assures long endurance. However, it is expensive compared with other alloys, but it provides better corrosion resistance in oxidizing corrosion than C4, C276, and 625 alloys.
  • Hastelloy C22 also provides corrosion resistance in acidic environments. Thus, it offers resistance to these round bars installed in seawater and high-chloride environments. 
  • Hastelloy C22 alloys enhance the fabrication and weldability properties. We can install these round bars in the industrial premises by standard welding, soldering, or forging methods.
