ASTM G78 Test Specimens

ASTM G78 Test Specimens

Metal test specimens used in ASTM G78 (Crevice Corrosion Testing of Iron-Base and Nickel-Base Stainless Alloys in Seawater and Other Chloride-Containing Aqueous Environments). These test specimens can be made from a range of different metal alloys and different configurations. Sizes up to 11.81” x 11.81” have been used, but smaller sizes as needed for lab apparatus are allowed. The sheared edges are machined or ground to remove deformed material. The specimen surface finish may be as rolled or surface ground 120 grit, or other as chosen.
