Features


Hastelloy C2000 This alloy is designed to withstand more corrosive chemicals, including sulfuric acid, hydrochloric acid, and hydrofluoric acid. Unlike previously optimized Ni-Cr-Mo alloys which are only resistant to oxidizing or reducing acids, C-2000 alloys are resistant to both environments. The combined action of molybdenum and copper (at the 16% and 1.6% levels, respectively) gives the alloy excellent resistance to reductive media corrosion, while the high chromium content (23% WT) guarantees the ability to corrode oxidizing media.
1. It is not appropriate to post-weld stress treatment of Ni-Cr-Mo alloy at about 650 °C. Generally, no heat treatment is required after welding, but if stress is required, it is recommended to perform complete solution annealing at 1149 ° C and then water quenching.
2, the alloy's hot processing temperature range of 1080 ° C -900 ° C, cooling method is water cooling or other rapid cooling. In order to ensure the best anti-corrosion performance, solution heat treatment should be carried out after hot working.

Metallographic Structure


Hastelloy C-2000 alloy is a face-centered cubic crystal structure. Its chemical composition guarantees metallographic stability and sensitization.

Applications


Hastelloy C2000 offers great potential for increased production. When used in the original Ni-Cr-Mo alloy, its enhanced corrosion resistance allows for longer equipment life at the same material thickness and a higher safety factor under more severe conditions. Increased corrosion resistance in all aspects allows the unit to be used in multiple applications (reactors, heat exchangers, valves, pumps, etc.) for a greater return on investment. For example, one reactor can be adapted to the hydrochloric acid mixture and then converted to another condition of the nitrate-based mixture. Because of the C-2000's ability, it is the best nickel-based alloy material that can adapt to a variety of processes.
