The corrosion tests carried out by AZTERLAN allow the accreditation and validation of materials and protection systems (coatings and treatments) against corrosion phenomena.
The tests offered by the area are carried out mainly under international UNE, ISO and ASTM standards and according to the specifications of clients from sectors as demanding as Oil & Gas, wind energy or the automotive industry, among others.
Stainless steels and CRA (corrosion resistant alloys).
- Aggressive media: Solutions with a high concentration of acids such as sulfuric or nitric, or with a high content of chlorides.
- Short duration.
Estimation of mass loss and visual inspection for defects caused by corrosion, such as cracks or pitting.
They allow to certify materials that must comply with resistance characteristics against corrosion. They are necessary to validate the material and ensure its behavior in service.
- Acid corrosion according to ASTM A262, ASTM G48, ASTM G28, ISO 3651, ASTM A923.
- Metallographic methods ASTM E562, ASTM A262.method A, ASTM A923.method A, NORSOK- ISO17781
Metallic and non-metallic coatings on steel and other materials.
Exposure under certain temperature and humidity conditions.
Additional information combined with other coating evaluation tests:
Adherence: crosscut cut according to ISO 2409.
Corrosion degree according to UNE EN ISO 10289 and ASTM D610.
Evaluation of defects according to UNE-EN ISO 4628.
They allow evaluating the resistance and behavior of different types of coatings against corrosion. The most commonly carried out in AZTERLAN are:
- Neutral Salt Spray Test according to ISO 9227 and ASTM B117.
- Condensate Vapor Test according to UNE EN ISO 6270 and ASTM D2247.
- Cyclic Corrosion Test: FORD CETP 00.00-L-467, VDA 621-415, VW PV1210, UNE-EN ISO 11997-1 (B), etc.
Low/medium alloy carbon steels in normalized state, or quenching and tempering.
Tests carried out without tension (HIC) or under tension (SSC).
Evaluation of the metallurgical quality and the manufacturing process against the generation of hydrogen cracks.
Tests for qualification of metallic materials resistant to cracking by SSC (Sulfide Stress Cracking) and HIC (Hydrogen Induced Cracking) specific for the OIL&GAS sector, according to NACE TM0177 and TM0284 standards.
- HIC: Evaluation of internal cracking type stepwise cracking.
- SSC: Resistance to stress cracking by means of tension ring and four point bending test methods.
