How do you test for intergranular corrosion?
Streicher Test (ASTM A262 Practice B)
The Streicher test, which is commonly used for stainless steel and nickel alloys, includes boiling the specimen in a Ferric Sulfate – Sulfuric Acid solution for 24-120 hours and assessing the results. Mass loss determines the degree of corrosion. Intergranular Corrosion (IGC) Test in Rabale
What is intergranular corrosion IGC )?
Intergranular corrosion (IGC) is a kind of localised corrosion that is distinguished by preferred corrosion at grain borders or nearby regions, with little or no assault on the grains. It, like other types of localised corrosion, occurs primarily on passive alloys exposed to particular corrodents.
