Intergranular corrosion is an efficient test for screening a material’s corrosion resistance under certain conditions. Using a variety of methods, including ASTM A262, we can provide critical data about corrosion resistance, detecting issues before they become catastrophes.

Intergranular corrosion refers to material degradation that occurs along the grain boundaries of metallic materials after exposure to environmental stress, such as extreme temperatures (a process called sensitization). While the damage may not be immediately visible, intergranular corrosion can cause loss of strength and integrity in a material, resulting in defects or critical failures. Testing can also reveal errors in the heat treating process, and highlight any areas where updates are needed.

Testing for Intergranular Corrosion

We test a range of metallic materials for intergranular corrosion, including stainless steel and aluminum, and alloys such niobium and chromium. Our experts have years of experience working with metallic materials and can assist in choosing the most appropriate method for testing. With proven expertise in corrosion testing, failure analysis and material properties testing across industries, we are the partner of choice for your intergranular corrosion testing program.
