Ding Testing Inspection: Stainless Steel Intergranular Corrosion Testing, Ensuring Material Safety and Reliability
In modern industry, stainless steel is widely used in fields such as chemical engineering, petroleum, food processing, and medical devices due to its excellent corrosion resistance. However, stainless steel materials can also undergo intergranular corrosion under certain conditions. This type of corrosion is often difficult to detect but can severely weaken the strength and durability of materials. Ding Testing Inspection is committed to providing professional stainless steel intergranular corrosion testing services to safeguard the safety and reliability of your 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 stainless steel intergranular corrosion testing services are based on the latest national standard GB/T 4334—2020 and international standards ISO 3651, using various advanced testing methods such as oxalic acid electrolysis, sulfuric acid-ferric sulfate method, and 65% nitric acid method to comprehensively evaluate the resistance of stainless steel materials to intergranular corrosion. Our services include not only material corrosion performance testing but also professional material selection advice and corrosion protection solutions.
Industry Pain Points
The occurrence of intergranular corrosion is closely related to factors such as material chemical composition, heat treatment processes, and usage environment. Without professional testing, the potential corrosion risks of materials are difficult to predict, and once corrosion occurs, it may lead to equipment damage, production interruptions, and even safety accidents.
Service Scope
Ding Testing Inspection's service scope is extensive, covering stainless steel intergranular corrosion testing, including but not limited to:
- Intergranular corrosion susceptibility assessment of stainless steel materials
- Intergranular corrosion performance testing of stainless steel welds
- Intergranular corrosion performance analysis during new material development
- Optimization suggestions for stainless steel material heat treatment processes
Application Fields
Ding Testing Inspection's stainless steel intergranular corrosion testing services are widely applied in the following industries:
- Petrochemical: Assessing the corrosion resistance of refining equipment, pipelines, and storage tanks
- Aerospace: Testing the corrosion resistance performance of key aircraft components
- Food processing: Ensuring the hygiene and safety of food contact surfaces
- Medical devices: Assessing the biocompatibility and corrosion resistance of medical equipment and tools
Testing Standards
Ding Testing Inspection conducts stainless steel intergranular corrosion testing in accordance with the following standards, ensuring the scientific, accurate, and authoritative nature of the test results:
- ASTM A262-2017 "Standard Test Method for Detecting Susceptibility to Intergranular Corrosion in Stainless Steels"
- GB/T 4334.5-2008 "Corrosion of Metals and Alloys—Methods for Determining the Susceptibility to Intergranular Corrosion of Stainless Steels"
- ISO 3651-2008 "Metallic Materials—Stainless Steels—Methods of Test for Susceptibility to Intergranular Corrosion"
By adhering to these standards, we can address the following technical issues
- Accurately assess the intergranular corrosion susceptibility of stainless steel materials
- Provide suggestions for material selection and process optimization
- Provide a scientific basis for material performance improvement and quality control
