Nickel Alloy 825 Heat Exchange Tube Chemical composition:
| % | Ni | Fe | Cr | C | Mn | Si | S | Mo | Cu | Ti | Al |
| min | 38 | 22 | 19.5 | 2.5 | 1.5 | 0.6 | |||||
| max | 46 | 23.5 | 0.05 | 1 | 0.5 | 0.03 | 3.5 | 3 | 1.2 | 0.2 |
Features: Alloy 825 has excellent resistance to chloride-ion-induced stress corrosion cracking, reducing environments containing phosphoric and sulfuric acids, oxidizing environments containing nitric acid and nitrates, and pitting, crevice corrosion and intergranular corrosion. It has good mechanical properties at cryogenic temperatures to moderately high temperatures up to 538℃
Where are nickel alloys used?
Highly corrosive environments
High temperature environments
High pressure environments
The main materials used in these environments are stainless steels, duplexes, etc. However, once the application is too critical and the risk of corrosion is high due to the medium, pressure and temperature, the decision is made to use a high nickel alloy such as alloy 825, 600, 625, 200, 400, C276.
The choice of a specific alloy depends on
The medium flowing through the pipeline and its corrosiveness
The temperature of the medium
The pressure in the pipe/preform
