    ASTM B564-2015 Nickel Alloy Forgings

     

    Alloy Type: Ni-Fe-Cr-Mo-Cu

     

    UNS Designation: N08825

     

    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 ℃.

     

    Applications

    Chemical process industry, acid production, picking equipment, pollution control equipment.

     

    Ordering Information

    It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specification. Examples of such requirements include, but are not limited to, the following:

    1 Alloy type.

    2 Condition.

    3 Quantity (mass or number of pieces).

    4 Forging, sketch or drawing.

    5 Certification-State if certification or a report of test results is required.

    6 Samples for Product (Check) Analysis—Whether samples for product (check) analysis should be furnished.

    7 Purchaser Inspection—If the purchaser wishes to witness tests or inspection of material at the place of manufacture, the purchase order must so state indicating which tests or inspections are to be witnessed.
