Corrosion Resistance:HASTELLOY® C-2000® alloy, developed as an optimized alloy for expanding material applications, originated from a conceptual idea of incorporating copper into the well-established Ni-Cr-Mo alloys. Since its market introduction at the end of 1995, it has continually received significant market approval due to its inherent versatility. Technological innovations not only improved the alloy's resistance to water corrosion but also expanded the overall application range of the NiCr-Mo alloy family. This new material is designed to resist a broader range of corrosive chemical substances, including sulfuric acid, hydrochloric acid, and hydrofluoric acid. Unlike previously optimized Ni-Cr-Mo alloys that could only resist either oxidative or reductive acids, the C2000 alloy has corrosion resistance to both environments. The combined action of molybdenum and copper (at levels of 16% and 1.6%, respectively) provides the alloy with excellent resistance to corrosion in reducing media, while the high chromium content (23%wt) ensures resistance to oxidative media corrosion. HASTELLOY® C-2000® alloy expands the range of applications for Ni-Cr-Mo alloys in various corrosive environments, exhibiting excellent corrosion resistance to oxidative media and outstanding resistance to reducing environments. The excellent performance of C-2000 has led to breakthroughs in the application of chemical industry equipment. Previously, attempts to fully optimize the corrosion resistance of Ni-Cr-Mo alloys achieved only partial success. High chromium content was used to resist oxidative media, such as iron ions, copper ions, and dissolved oxygen. For reducing media, such as dilute hydrochloric acid or sulfuric acid, high molybdenum + tungsten content was required. The limitations of metallurgical stability made it difficult to simultaneously optimize both.
