Heat treatment

After hot working, forgings shall be cooled to a temperature below 538℃ prior to heat treating. Heat treatment of forgings may be performed before machining. The purchaser shall specify the heat-treatment method, and the manufacturer shall provide a test report included a statement of the heat-treatment method employed.

Corrosion testing

Corrosion testing is not required by ASTM A182 specification.

Austenitic grades shall be capable of meeting the intergranular corrosion test requirements in accordance with practice E of A262.

Intergranular corrosion tests shall be performed on specimens of ferritic stainless steels according to A763.

Finished surface

The forgings shall be free of scale, machining burrs which might hinder fit-up, and other injurious imperfections. The forgings shall have a workmanlike finish, and machined surfaces shall have a surface finish not to exceed specified roughness height, other than surfaces having special requirements.
