Ding Testing Inspection: Intergranular Corrosion A Test, The Invisible Shield Guarding the Heart of Metals
Intergranular corrosion of metals and alloys, like an invisible killer of industrial equipment, silently erodes the structural integrity of materials. Ding Testing Inspection uses Intergranular Corrosion A Test technology to unveil this hidden threat, ensuring the safety and durability of metal materials.
Service Introduction
Since 2023, Ding Testing Inspection (DTI) has been witnessing more than 500 batches of material inspection and corrosion tests annually by internationally renowned inspection agencies, with supervision from well-known inspection agencies, recognition from leading international users, and endorsement from top-tier manufacturers and engineers in the industry!
Ding Testing Inspection's Intergranular Corrosion A Test service is a corrosion sensitivity assessment technique specifically for austenitic stainless steel and duplex stainless steel. The Intergranular Corrosion A Test, also known as the 10% oxalic acid immersion test method, involves electrolytic immersion of the sample in a 10% oxalic acid solution, followed by observation of the etched surface under a microscope to determine whether long-duration heat acid tests such as Method B, Method C, Method D, and Method E are necessary. This method simulates the extreme conditions that materials may encounter in actual use through rapid cooling at high temperatures, thereby accurately predicting the material's resistance to intergranular corrosion.
Industry Pain Points
Intergranular corrosion typically occurs after welding or other heat treatment processes, where carbides precipitate along grain boundaries, increasing the local corrosion sensitivity of the material. In industries such as petrochemical, marine engineering, and nuclear power generation, this corrosion can lead to equipment failure and even safety accidents, causing significant economic losses and safety risks to companies.
Service Scope
Ding Testing Inspection's service scope is extensive, covering Intergranular Corrosion A Test, including but not limited to:
- Intergranular corrosion susceptibility assessment of stainless steel materials
- Corrosion resistance performance testing during new material development
- Corrosion resistance performance verification after material surface treatment
- Corrosion cause diagnosis in material failure analysis
Application Fields
Ding Testing Inspection's Intergranular Corrosion A Test services are widely applied in the following industries:
- Petrochemical: Assessing the corrosion resistance of refining equipment, pipelines, and storage tanks
- Marine engineering: Ensuring the long-term stability of materials for offshore platforms and subsea facilities
- Aerospace: Testing the corrosion resistance performance of key aircraft components
- Energy industry: Assessing the corrosion resistance of wind turbines and nuclear power station equipment
Testing Standards
Ding Testing Inspection conducts Intergranular Corrosion A Test in accordance with the following standards, ensuring the scientific, accurate, and authoritative nature of the test results:
- GB/T 4334-2020 "Corrosion of Metals and Alloys - Methods for Intergranular Corrosion Test of Stainless Steels"
