ASTM B564-2015 Nickel Alloy Forgings

Alloy Type: Low-carbon Ni-Mo-Cr

UNS Designation: N10276 （Alloy C-276）

Features

Alloy C-276 has excellent resistance to localized corrosion, stress corrosion cracking, and to both oxidizing and reducing media, thus making it suitable for a wide variety of chemical process environments, including ferric and cupric chlorides, hot contaminated media(organic and inorganic), formic and acetic acids, seawater and brine solutions. It is one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.

Applications

Chemical processing, waste treatment, pollution control pulp and paper production, and marine engineering.

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.
