Corrosion Testing

Corrosion is the process of the deterioration of a material due to chemical reaction, with its surrounding environment.  Corrosion testing is performed to assess the susceptibility of a material to environmental attack and quantify a material’s resistance to a corrosive environment. A corrosion test subjects a sample of material to a severe test environment (a combination of temperature and solution) for a specified time. Following exposure to a severe test environment, a test sample is evaluated for signs of corrosive attack. Typically, visual inspection for pitting, loss of mass, and bend resistance are assessed to evaluate if a sample has resisted corrosive attack.

Accu-Test Labs routinely performs the following corrosion testing:

Intergranular Attack in Austenitic Stainless Steels per ASTM A262 – Practice A, B, C, E, F

Intergranular Corrosion in Wrought, Nickel-Rich, Chromium-Bearing Alloys per ASTM G28 Method A

Pitting and Crevice Corrosion Resistance of Stainless Steels in Ferric Chloride Solution per ASTM G48 Method A, B, D

Detrimental Intermetallic Phase in Duplex Stainless Steels per ASTM A923 Method A, C
