Frequently Asked Questions
Q: What is Hastelloy C2000 (UNS N06200)?
Hastelloy C2000 (UNS N06200 / 2.4675 / Alloy 2000) is a nickel-chromium-molybdenum alloy with 1.6% copper, offering superior resistance to sulfuric acid at all concentrations while maintaining excellent performance in hydrochloric acid and oxidizing environments.
Q: What is the difference between Hastelloy C2000 and C276?
C2000 adds 1.6% copper giving it superior sulfuric acid resistance. C276 (N10276) has higher molybdenum for reducing media. C2000 covers both oxidizing and reducing acid environments in a single alloy - eliminating the need for two separate alloys in mixed-acid processes.
Q: What are the main applications of Hastelloy C2000 pipe?
Chemical processing reactors, heat exchangers handling H₂SO₄/HCl, flue gas desulfurization (FGD) systems, pharmaceutical API manufacturing, aerospace combustion components, and offshore/marine pipework.
Q: What product forms are available for Hastelloy C2000?
Seamless & welded pipe & tube (ASTM B622/B619), plate, sheet & strip (ASTM B575), round bar & rod (ASTM B574), pipe fittings (elbows, tees, reducers, caps per ASTM B366), and flanges (ASME B16.5). EN 10204 3.1 mill test certificates available.
Q: Can Hastelloy C2000 be welded?
Yes. C2000 can be welded using TIG/GTAW and MIG/GMAW processes. Use ERNiCrMo-17 filler metal, minimize heat input to prevent carbide precipitation, and solution anneal at 1121–1177°C with rapid water quench after welding if full corrosion resistance is critical.
