Adding copper, and adjusting the proportions of chromium and molybdenum are the tricks to give C-2000 an edge over chlorides, crevice attack, and stress corrosion cracking in chloride-bearing solutions. Even though both are nickel-chromium-molybdenum alloys with great resistance, C-2000 usually gives better resistance to reducing chemicals and process streams with ferric ion contamination.
What about welding of Hastelloy C2000 (weld compatibility of uns n06200)?
Definitely, Hastelloy C-2000 can be welded with the usual welding methods if the right procedures are followed. For UNS N06200, it is necessary to monitor the interpass temperatures closely, use the same filler metals with the alloy’s resistance to localized corrosion and stress corrosion cracking properties, and apply post-weld treatment depending on the service conditions to make sensitization less and preserve excellent resistance to chloride-induced stress corrosion.

The alloy’s composition—especially its chromium and molybdenum content combined with copper—provides Hastelloy C-2000 with extraordinary resistance to chloride-induced stress corrosion cracking as well as resistance to chloride-induced pitting and crevice attack. It performs adequately in chloride-bearing solutions, and it demonstrates a level of resistance to stress corrosion cracking that is greater than that of many other corrosion-resistant alloys when being utilized in chloride-contaminated process streams.
What are the main chemical processing and industrial sectors where Hastelloy C2000 is widely used?
Hastelloy C-2000 is rediscovered support and is again widely used in chemical process equipment, which includes reactors, heat exchangers, piping, and valves, mainly in the presence of sulfuric acid, hydrofluoric acid, chlorides, and other corrosive chemical environments.

What are the advantages of copper addition in Hastelloy C2000 performance?
Copper is one of the elements implanted in Hastelloy C-2000 which is this and copper is the one that makes nickel-chromium-molybdenum alloys driving them towards the excellent performance apex. Hence, copper together with molybdenum and chromium creates the alloy’s attributes of excellent corrosion resistance to reducing media, thereby making it an alloy that is to be always applied where other nickel-chromium-molybdenum alloys may be less effective.
Are there limitations to Hastelloy C2000—the media it cannot handle?
Hastelloy C-2000, along with its outstanding resistance to a wide range of corrosive chemicals, still cannot be considered a universally resistant material. The extremely strong oxidizers at high temperatures or highly concentrated oxidizing environments may favor electrically conducting high-chromium or specialized alloys. On the other hand, Hydrofluoric acid at certain concentrations and temperatures poses a risk and, thus, alternative materials or coatings may be necessary.
