PONTLAB performs specialized Stress Corrosion Cracking (SCC) testing to evaluate the susceptibility of metals and alloys to premature brittle failure under combined mechanical stress and corrosive environments. Our laboratory simulates extreme sour service and industrial conditions, including prolonged exposure to highly aggressive media such as Hydrogen (H₂), Hydrogen Sulfide (H₂S), Ammonia (NH₃), and Carbon Dioxide (CO₂ ). We support global manufacturers in validating materials for Oil & Gas, aerospace, and chemical processing, ensuring full compliance with international standards including NACE TM0177, NACE TM0198, and ASTM G129.
Our laboratory performs these specialized evaluations on corrosion-resistant alloys (CRA), stainless steels, and high-nickel materials. To guarantee the highest level of technical expertise and regulatory compliance, all testing programs and failure investigations are supervised by our internal staff, certified as Corrosion Experts by AMPP (formerly NACE).
SCC testing is critical for validating innovative components and materials across demanding industries, with a primary focus on upstream and downstream Oil & Gas extraction.

An accelerated methodology for determining environmental cracking susceptibility. Compared to constant-load tests, SSRT applies a slow, continuous deformation inside HPHT Hastelloy autoclaves, accelerating failure mechanisms in controlled environments containing H₂S, H₂, CO₂ e NH₃.
Constant load testing on metallic specimens in chloride solutions saturated with sour gases (H₂S, H₂, NH₃, CO₂ ). Capabilities include ambient pressure/temperature per NACE TM0177 Method A, and HPHT autoclave testing up to severity Level VII.
Standard uniaxial tensile testing to evaluate sulfide stress cracking (SSC) susceptibility in sour H₂S environments. Our laboratory staff co-authored the ScienceDirect Study [Improvement of the Test Equipment for a Stress Corrosion Lab through the Axiomatic Design](href="https://www.sciencedirect.com/science/article/pii/S2212827115008264) dedicated to optimizing this testing equipment to maximize data accuracy.

High Pressure High Temperature (HPHT) testing up to 103 bar and 210°C inside 15-liter Hastelloy autoclaves. The chamber accommodates standard specimens, finished components, or stressed samples using 3/4-point bending and C-rings to evaluate metals, polymers, and coatings.
Accelerated testing to simulate marine environments through cyclic wetting and drying in salt solutions. Widely applied in Aerospace, Defense, and Marine sectors to evaluate susceptibility to stress corrosion cracking (SCC), pitting, and intergranular corrosion, specifically on high-strength aluminum alloys.
Evaluation of hydrogen damage resistance via HIC testing per NACE TM0284. The test analyzes internal cracking and material blistering caused by atomic hydrogen within the crystal lattice — a critical verification for Oil & Gas and Energy sectors to prevent catastrophic failures in sour service.
Accelerated NH₃ exposure testing to evaluate specific stress corrosion cracking (SCC) and season cracking in metals, alongside swelling and degradation in polymers and coatings. Critical validations for the energy transition, green ammonia shipping, and automotive SCR systems.
All analyses can be structured in a completely customised manner, based on customer requirements. We offer tailor-made tests for materials, conditions of use and required regulations, ensuring reliable and targeted results.
