Corrosion and protection of materials

Accreditation and validation of materials in compliance with international standards.

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.

International Standards of reference

Main testing services

Intergranular and pitting corrosion

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.

Environmental testing

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:

Hydrogen fragilization susceptibility in sulfhydric acid (H2S)

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.

Specialization fields

Fatigue and fracture mechanics

Analysis of the apparition and evolution of cracks.

Fastening elements

Bolts, nuts and threading elements.

Welded joints

Testing, inspection, training and much more.

Diagnosis of defects and failures in service
Forensic analysis of the origin of defects and premature failures.
