Cost Considerations
Hastelloy C4 cost is higher than Hastelloy C2000.
Hastelloy C-2000 is a nickel-chromium-molybdenum alloy that has been specially designed to exhibit excellent corrosion resistance in both oxidizing and reducing environments. Its high chromium content (22.0% – 24.0%) and the addition of copper (1.3% – 1.9%) enhance its resistance to corrosion in aggressive media. This alloy is particularly suitable for applications involving sulfuric acid, hydrofluoric acid (HF), and chloride solutions, outperforming traditional stainless steels and other alloys in these environments.
Hastelloy C-4, on the other hand, excels in intergranular corrosion resistance in extreme corrosion environments. While it also possesses good corrosion resistance in both oxidizing and reducing media, its specific formulation may make it a better choice for applications where intergranular corrosion is a critical concern.From a cost standpoint, the choice between these two alloys often comes down to the specific requirements of the application.
Processing Costs
The processing costs of Hastelloy C-2000 and Hastelloy C-4 can vary depending on the specific fabrication techniques required. Both alloys can be hot and cold worked, but the addition of copper in Hastelloy C-2000 may necessitate more careful control during processing to avoid damage due to overheating. Welding of both alloys is generally straightforward, with conventional welding methods such as TIG and MIG being applicable. However, post-weld heat treatment may be required to restore material properties, which can add to processing costs.
Maintenance Expenses
The long-term maintenance expenses associated with Hastelloy C-2000 and Hastelloy C-4 will largely depend on the severity of the operating environment and the alloy’s ability to withstand corrosion. Hastelloy C-2000’s broad corrosion resistance profile may result in lower maintenance costs over time in many applications, as it can better withstand the effects of aggressive chemicals and high temperatures. However, in environments where intergranular corrosion is a significant issue, the superior resistance of Hastelloy C-4 may lead to fewer repairs and replacements, thereby offsetting its higher initial cost.
