What is Hastelloy c22 pipe ?

Alloy C22 is a super alloy of nickel, chromium and molybdenum, which has been solid solution strengthened. It also has iron, tungsten and cobalt added to the alloy, which influences the properties of C22. Hastelloy c22 pipe shows great resistance to oxidation and corrosion.

They have good fabricability and possess enhanced mechanical properties in a wide range of temperatures. The EN 2.4602 cold drawn pipe shows good resistance to hydrochloric acids in all concentrations from ambient to high temperatures. They can resist different forms of corrosion including pitting, crevice and stress corrosion cracking.

The nickel C22 hot finished pipe should be used within 1250 °F or the detrimental phases can form. The pipes are widely used in marine applications as C22 can resist aqueous corrosion in stagnant and flowing salt water. They have good weldable properties too. The 2.4602 Hastelloy C22 clad pipe has a standard thickness range of 0.038 to 0.141” and can be used in pollution control and chemical processing sectors.

What is the cost of alloy c22 pipe in india?

The alloy c22 pipe is more expensive than standard stainless steel pipe due to its chemical composition and properties. It has costly elements like nickel, chromium, molybdenum, tungsten, etc., which enhances the corrosion resistance properties. However, the exact price of pipes can vary with the Hastelloy c22 pipe supplier, their internal costing strategies and market conditions. Factors like size and dimensions, customization, quality, additional testing requirements and delivery location can also alternate the price. Renowned suppliers like Regent Steel & Engineering Co. offer high quality UNS N06022 cold finished pipes at a competitive rate.

How do you identify Hastelloy c22 seamless pipe?

To ensure the pipe material is alloy C22 and its quality, you should:

  • Purchase from a reputed and reliable manufacturer like Regent Steel & Engineering Co. Apart from getting assured quality, you can ask for material certificates to ensure the characteristics of the seamless Hastelloy alloy C22 annealed pipe.
  • Check the pipe for any kind of marking with information like material name, manufacturer’s logo, etc.
  • Hastelloy c22 seamless pipe has a distinctly bright and shiny appearance.
  • You can go for third party inspection, if required or you have any doubt about the material or its quality.
  • You can use technology like metallography to examine the microstructure and confirm the metallurgical structural presence of C22 material.
How can you tell the difference between stainless steel and Hastelloy c22?
  • Stainless steel and Hastelloy c22 materials have different appearances. SS is shiny grey or silver, whereas C22 is brighter.
  • UNS N06022 pipe material has a more complex metallurgical structure than standard stainless steel.
  • They have different alloy compositions and are hence used for separate applications. Hastelloy 2.4602 square pipe is preferred for more corrosion resistant and aggressive chemical environments like chemical and petrochemical industries.
Is nickel alloy C22 welded pipe easy to machine ?

The nickel alloy C22 welded pipe is hard to machine due to its high strength and toughness. The C22 material has a tendency to work harden during machining. Also, the DIN 2.4602 round pipe material has a complex alloy composition which can reduce machinability. It also has a low thermal conductivity which can cause heat buildup during machining.
