Hastelloy C2000 (UNS N06200) is a nickel-based corrosion-resistant alloy that has excellent resistance to a variety of highly corrosive media through optimized composition (such as high chromium, molybdenum, copper and extremely low carbon content), especially in mixed acid environments.
Applications of Hastelloy C2000 Plate
Chemical Processing and Pharmaceutical Manufacturing
In reactors, heat exchangers, and piping systems, alloy C2000 is chosen for its ability to withstand both oxidizing and reducing acids such as sulfuric, hydrochloric, and hydrofluoric acids.
Petrochemical and Oil & Gas Industries
The alloy is widely used in components that handle aggressive environments, such as downhole equipment, valves, and reactor vessels. Its resistance ensures reliability under high pressures and varying temperatures, even in sour gas conditions.
Marine and Offshore Applications
Hastelloy C2000's robust resistance to seawater corrosion-including crevice and pitting corrosion-makes it suitable for offshore platforms, shipbuilding, and marine cooling systems.
Aerospace and Power Generation
In these industries, components such as turbine casings, boiler parts, and heat exchangers require materials that can perform at elevated temperatures without degradation. Hastelloy C2000 ensures continued performance and minimal downtime.
Environmental and Pollution Control
The material's ability allows for its application in flue gas desulfurization systems, acid conditioning setups, and other pollution control equipment.
Features of Alloy C2000
Broad-spectrum corrosion resistance: Excellent corrosion resistance to both oxidizing acids (nitric acid, mixed acid) and reducing acids (hydrochloric acid, sulfuric acid), superior to traditional C series alloys (such as C-276);
Local corrosion resistance: High chromium (23%) improves resistance to pitting and crevice corrosion, and molybdenum (16%) and copper (1.6%) enhance resistance to reducing acids;
Processing and weldability: Low-carbon design reduces intergranular corrosion tendency and is suitable for complex structure manufacturing.
Fabrication of UNS N06200 Plate
One of the practical advantages of alloy C2000 is its excellent fabricability. It can be hot or cold worked into various forms such as sheets, plates, coils, and foils. The alloy shows good formability when solution annealed and can be processed by standard metalworking techniques.
Machining of Alloy N06200 Sheet
Machining Hastelloy C2000 plate is challenging due to its high strength and the tendency to work harden. Specialized cutting tools-often carbide-tipped tools-and optimized machining parameters (such as lower speeds and appropriate feeds) are recommended to minimize tool wear and to achieve a high-quality finish.
Welding of Alloy 2.4675
The weldability of Hastelloy C2000 is among its notable features. It is compatible with various welding processes including Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), and Shielded Metal Arc Welding (SMAW). Its homogeneous microstructure allows welding to be performed without post-weld heat treatment under most circumstances, though care must be taken during welding to minimize the heat input. Pre-cleaning of the surfaces and controlled interpass temperatures (typically below 93 °C or 200 °F) help maintain its corrosion resistance in the heat-affected zones.
