Intergranular Attack or End Grain pitting

Intergranular corrosion and end grain pitting can compromise the integrity of stainless steels and nickel-based alloys, leading to premature material failure. At Advanced Engineering Consultancy and Testing Laboratory (AECTL), we provide ISO 17025 NATA-accredited testing for detecting and evaluating these corrosion mechanisms by:

✔ AS 2205.10.1 – Detection of intergranular corrosion in stainless steel weldments.

✔ ASTM A262 Practices A & C – Evaluating susceptibility to intergranular attack in austenitic stainless steels.

✔ ASTM F2111 Sections 7.4, 7.5, 7.6 – Testing methods for end grain pitting and localized corrosion in surgical implants and medical-grade alloys.

Our Intergranular Corrosion & Pitting Analysis Includes:

✅ Oxalic Acid Etch Test (ASTM A262 Practice A) – Rapid screening for susceptibility to intergranular attack.

✅ Nitric Acid & Electrochemical Tests (ASTM A262 Practice C, ASTM F2111) – Advanced analysis of grain boundary corrosion resistance.

✅ Microscopic Examination – High-resolution imaging for assessing corrosion morphology and depth.

✅ Material Compliance & Failure Investigation – Supporting industries in quality control, failure prevention, and material selection.

With our ISO 17025 accreditation, we ensure precise, reliable, and industry-compliant corrosion testing to help manufacturers, fabricators, and industries maintain material integrity and performance.
