Steel Industry Glossary › IGC TestWhat is the purpose and process of the IGC test in industrial applications? The IGC test, or Intergranular Corrosion test, assesses resistance to intergranular attack in materials. It is critical for stainless steels and alloys, adhering to standards like ASTM A262 and ISO 3651-2. The test involves immersing samples in a corrosive medium and evaluates corrosion rates, ensuring materials are safe for use in critical environments.
IGC Test Intergranular Corrosion test (ASTM A262 Practice E) — evaluates the susceptibility of austenitic stainless steels to intergranular corrosion due to sensitization.
