Intergranular Corrosion (IGC) Testing
Professional Intergranular Corrosion (IGC) testing services to evaluate the susceptibility of stainless steels and corrosion-resistant alloys to grain boundary corrosion, ensuring long-term reliability and compliance with international standards.
Accurate Intergranular Corrosion Evaluation
Intergranular Corrosion (IGC) Testing is performed to determine whether stainless steels and corrosion-resistant alloys are susceptible to corrosion along their grain boundaries due to carbide, nitride or intermetallic phase precipitation.
At Om Metalab, our metallurgical experts carefully select the appropriate ASTM A262 practice based on the material grade, heat treatment condition and expected service environment. This ensures accurate evaluation and dependable test results.
Our testing services help manufacturers verify material integrity, optimize heat treatment processes and ensure compliance with industrial quality requirements before products are put into service.
ASTM A262 Testing Practices
Our laboratory performs multiple ASTM A262 practices based on the material composition and corrosion evaluation requirements.
Practice A
Oxalic Acid Etch Test used as a rapid screening method to examine grain boundary structure and identify carbide precipitation in stainless steels.
Practice B
Streicher Test using Ferric Sulfate and Sulfuric Acid to evaluate intergranular corrosion resistance through controlled weight-loss measurement.
Practice C
Huey Test utilizing repeated Nitric Acid exposure to assess corrosion resistance, heat treatment quality and chromium depletion.
Practice E & F
Strauss and Copper Sulfate tests evaluate susceptibility to intergranular corrosion through bend testing and weight-loss analysis for stainless steel materials.
Importance of Intergranular Corrosion Testing
Intergranular corrosion can significantly reduce the strength and service life of stainless steel components, even when the surface appears unaffected. Detecting this condition early helps prevent costly failures in critical industrial applications.
IGC testing verifies material quality, confirms proper heat treatment and ensures components will perform reliably in corrosive service environments.
