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:
ASTM A262 – Detecting Susceptibility to Intergranular Attack in Austenitic Stainless Steels.
ASTM G28 – Detecting Susceptibility to Intergranular Corrosion in Wrought, Nickel Rich, Chromium-Bearing Alloys.
ASTM G48 – Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by Use of Ferric Chloride Solution.
ASTM A923 – Detecting Detrimental Intermetallic Phase in Duplex Austenitic/Ferritic Stainless Steels.
