HastelloyC-2000 Material introduction

HastelloyC-2000（UNS N06200）As an optimized alloy developed to expand the application scope of materials, the alloy began with a conceptual idea of adding copper to the well-established Ni Cr Mo alloy. Since it entered the market at the end of 1995, it has been continuously recognized by the market, thanks to its inherent versatility. The technical innovation not only improves the resistance of the alloy to water corrosion, but also expands the overall application range of Ni Cr Mo family alloys. It is designed to resist more corrosive chemicals, including sulfuric acid, hydrochloric acid and hydrofluoric acid. Unlike the previously optimized Ni Cr Mo alloy, which can only resist oxidizing or reducing acids, HastelloyC C-2000 alloy is resistant to corrosion in both environments. The combined action of molybdenum and copper (at the level of 16% and 1.6% respectively) makes the alloy have excellent resistance to reducing medium corrosion, and the high chromium content (23% wt) ensures the resistance to oxidizing medium corrosion. From an engineering perspective, Hastelloy C-2000 offers great potential to improve production. When used in the original Ni Cr Mo alloy, its enhanced corrosion resistance can achieve longer equipment life under the same material thickness and higher safety factor under worse conditions. The improvement of corrosion resistance in various aspects enables the equipment to be used for multiple purposes (reactors, heat exchangers, valves, pumps, etc.), thus receiving greater return on investment. For example, a reactor can adapt to another working condition of hydrochloric acid mixture and then convert it into nitric acid based mixture. Hastelloy C-2000 is the best nickel base alloy material that can adapt to various processes due to its various talents.

HastelloyC-2000 Heat treatment process

The proper heating temperature is about 1150 ℃. After heat preservation, it is cooled by water. For Ni Cr Mo alloy, stress relief after welding cannot be carried out within the range of sensitization temperature. In order to eliminate residual stress, solution treatment must also be carried out.
