If materials with incorrect heat treatment enter service, they are liable to crack or fail by intergranular corrosion IGC much more rapidly than properly treated materials; ASTM A is a screening test to help find batches that are incorrectly processed. Intergranular corrosion shows up as the dark black lines around the grain boundaries. We provide accurate, repeatable results along with world-class customer service.
