Hastelloy C22 comes with good weldability and shows high resistance to grain boundary precipitate.This means the Hastelloy C22 tube can be used in as-welded condition.However, the maximum operating temperature for C22 tube is 1250 °F or else they can form detrimental phases.
This will make the EN 2.4602 boiler tube lose several of its essential properties.The tubes are made in compliance to ASTM B626 and ASME SB626 specifications.They are available in standard sizes of ¼ - 4".Clients can ask for custom dimensions, but that can increase the cost and delivery timelines of UNS 6022 superheater tubes.
The 2.4602 Hastelloy C22 extruded tube is known for its good resistance in oxidizing and reducing media.They can also resist aqueous corrosion in wet chloride and nitric acid mixtures due to the presence of nickel.The material can withstand different types of chemical acids, sea water, brine and various organic & inorganic contaminated solutions.Thus, the Hastelloy alloy C22 annealed tube is found in chlorinated systems, pharmaceutical industries, etc.
The material equivalents of alloy C22 tubes are NiCr 21 Mo 14W and WERKSTOFF NR.2.4602.They offer good corrosion & oxidation resistance and have high temperature strength.The material is quite weldable and can be used in different critical applications.

The Hastelloy C22 seamless tube is suitable for applications that require high corrosion resistance and elevated temperature strength in aggressive environments.The seamless nickel alloy C22 square tubing can be used in applications like chemical processing, petrochemical, pharmaceutical, waste treatment, marine, aerospace, etc.
C22 is more expensive standard stainless steel grades.The DIN 2.4602 redrawn tube supplier offers them at different prices based on their internal pricing strategies and market conditions.The higher price is due to the alloy composition and unique properties of C22.The production procedure, size & dimension, customization, testing requirements and delivery location also has an impact on the price.You can contact reliable manufacturers like Regent Steel & Engineering Co.to get C22 tubes at the most competitive rate.
