Introduction

Hastelloy C-2000 is a versatile corrosion resistant alloy with excellent uniform corrosion resistance in both oxidizing and reducing environments. Resistant to pitting corrosion, crevice corrosion and stress corrosion cracking over a wide temperature range, especially hydrochloric, sulfuric and hydrofluoric acids, as well as chloride and halide solutions.Unlike the previous optimized Ni-Cr-Mo alloys that are only resistant to oxidizing or reducing acids, Hastelloy C-2000 alloy is 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 corrosion in reducing media, while high chromium content (23%wt) ensures resistance to corrosion in oxidizing media . From an engineering perspective, the Hastelloy C-2000 offers great potential to increase production. When used in place of the original Ni-Cr-Mo alloy, its enhanced corrosion resistance can obtain longer equipment life under the same material thickness, and can also obtain a higher safety factor under harsher conditions. The improvement in corrosion resistance in all aspects allows the equipment to be used for multiple purposes (reactors, heat exchangers, valves, pumps, etc.), resulting in a greater return on investment. For example, one reactor can be adapted to a hydrochloric acid mixture and then converted to a nitric acid-based mixture in another condition. Due to the various abilities of HastelloyC-2000, it is the best nickel-based alloy material that can adapt to a variety of processes.
