ASTM B564 UNS N08825, Ni-Fe-Cr-Mo-Cu also known as Incoloy 825, is a high nickel alloy that is used in high corrosion and high temperature applications. It has different designations in different countries: ASTM B424 Gr. UNS N08825(US), DIN 17750 Gr. 2.4858, JIS G4902 Gr. NCF 825.
ASTM B564 Standard Specification for Nickel Alloy Forgings
This specification covers nickel alloy forgings. These alloys are classified into different grades according to their chemical composition. A chemical analysis shall be employed on each alloy in order to determine its chemical composition. Grain size and mechanical properties like tensile strength, yield strength, and elongation shall be measured. A tension test and nondestructive ultrasonic test shall be done on each specimen.
Incoloy 825 Flange 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℃.
