1.What is Hastelloy C 2000 material?
Hastelloy C - 2000 is a nickel - based superalloy mainly composed of nickel, molybdenum, and chromium, with a nickel content of about 55%. It is designed to resist a wider range of corrosive chemicals, including sulfuric acid, hydrochloric acid, and hydrofluoric acid. The combined effect of molybdenum (16%) and copper (1.6%) gives the alloy excellent resistance to reducing media, while the high chromium content (23% wt) ensures resistance to oxidizing media. Its applications include flue - gas desulfurization systems, pharmaceutical industry reactors and dryers, as well as reactors, heat exchangers, columns, and pipelines in the chemical process industry
.2.What is the equivalent of Hastelloy c 2000?
The equivalent grades of Hastelloy C - 2000 are UNS N06200 and W.Nr. 2.4675
3.What are the grades of Hastelloy C?
Common grades of Hastelloy C series include C, C - 276, C - 4, C - 22, and C - 2000
. There are also some related alloys such as Inconel 625, Inconel 686, and VDM59, which also belong to the Ni - Cr - Mo alloy category of Hastelloy C series to a certain extent.
4.What is the difference between Hastelloy C and alloy 20?
Hastelloy C and Alloy 20 have the following differences. In terms of composition, Hastelloy C is a nickel - based alloy, mainly containing nickel, chromium, molybdenum, and other elements, while Alloy 20 is a nickel - iron - chromium alloy, with a relatively high iron content and also containing copper and molybdenum. In terms of corrosion resistance, Hastelloy C has excellent resistance to a variety of strong acids, chlorides, and high - temperature fluids, and performs well in both oxidizing and reducing environments. Alloy 20 also has good corrosion resistance, especially resistant to sulfuric acid and phosphoric acid, but its overall corrosion resistance in extremely harsh environments is generally not as good as that of Hastelloy C. In terms of application, Hastelloy C is often used in high - end and harsh - environment applications such as chemical processing, oil and gas refining, and marine engineering. Alloy 20 is more commonly used in chemical fertilizer, pharmaceutical, and food processing industries, as well as some general - purpose chemical equipment.
