ABOUT
Intergranular Corrosion (IGC) or Intergranular Attack (IGA), is an efficient test for screening a material’s corrosion resistance under certain conditions. Using a variety of methods, including ASTM A262, ASTM G28 and ASTM A763, we can provide critical data about the metals corrosion resistance to prevent failures in the field.
Intergranular corrosion refers to material degradation that occurs along the grain boundaries of metallic materials after exposure to a corrosive environment. The sustainability of certain stainless steels to IGC can be influenced by prior thermal processing and welding, which is referred to as 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.
Element’s intergranular corrosion testing helps reveal errors of batches that are incorrectly processed, and highlight any areas where updates are needed.
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.
Intergranular Corrosion (IGC) testing
We utilize different chemicals and test conditions to evaluate a range of metallic materials for intergranular corrosion, including stainless steel (austenitic, duplex and ferritic grades), nickel alloys and aluminum alloys.
Our Engaged Experts have years of experience working with metallic materials and can assist in choosing the most appropriate method for evaluating the intergranular corrosion resistance of your material.
