Incoloy 825
Features:
UNS Number N08825
Incoloy 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℃.
Applications:
Chemical process industry, acid production, pickling equipment, pollution control equipment.
