Intergranular Corrosion Testing

IGC testing, or intergranular corrosion testing, is a method for evaluating the corrosion resistance of materials in a specific environment. This test is commonly used to assess the performance of materials in applications where corrosion is a concern, such as oil and gas, chemical processing, and marine environments.

The IGC test is typically performed by immersing a specimen of the material being tested in a corrosive solution and measuring the depth of corrosion penetration over time. The test is often conducted at various temperatures and humidity levels to evaluate the material’s corrosion resistance under different conditions.

Several reference standards are commonly used to guide IGC testing, including ASTM G28, ASTM G48, and ISO 3651-2. These standards outline the specific procedures and requirements for conducting IGC testing, including the corrosive solution’s type and concentration, the test’s duration, and the methods for measuring corrosion penetration.

IGC testing is an essential tool for understanding the corrosion resistance of materials in real-world applications. Whether you are an engineer designing a new product or a materials scientist studying the properties of a particular material, IGC testing can provide valuable insights into the performance of the material in corrosive environments.
