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.
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.

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