Specialized material testing for hydrogen applications
We offer customized material tests for metals, plastics and elastomers that are specifically tailored to the requirements of hydrogen technologies. Our test methods provide meaningful data on the safety, durability and reliability of materials under realistic conditions.
Hollow tensile specimen measurements
Our hollow tensile specimen measurements provide precise and reliable results for analyzing the mechanical properties of materials under the influence of hydrogen. These measurements provide you with valuable data on the following aspects:
- Tensile strength: Determination of the strength of materials under tensile load.
- Ductility: Investigation of the ductility and deformability of materials.
- Sensitivity to hydrogen embrittlement: Identification of material failure due to the influence of hydrogen (in accordance with ISO 7039).
Our measurement methods allow you to accurately assess the performance and reliability of your materials under extreme conditions.
KJIC regulations
The determination of the fracture toughness parameter KJIC provides crucial information on crack initiation and propagation in materials exposed to hydrogen (according to ASTM 1820). This measurement helps you to precisely evaluate material integrity and identify potential risks in material behavior at an early stage.
- Crack initiation: Analysis of the onset of crack formation under the influence of hydrogen.
- Crack propagation: Investigation of the expansion and stability of cracks in the material.
- Material integrity: Assessment of the long-term stability and safety of materials.
Benefit from a detailed analysis that supports you in the selection and use of materials under extreme conditions.
da/dN measurements
We analyze fatigue crack growth (da/dN) and the threshold value ∆Kth under cyclic loading in hydrogen-containing environments - in accordance with the internationally recognized ASTM E647 standard. These tests enable:
- Reliable service life assessments of components and materials
- Safe material selection for applications with hydrogen exposure
- Sound decision-making basis for engineering and development
Our high-precision da/dN measurements provide you with reliable data on crack propagation speed to detect early damage and minimize risks.
Ripple Load Tests
Our ripple load tests with hollow tensile specimens enable the precise evaluation of the crack resistance of materials under the influence of small cyclic load fluctuations in a hydrogen-containing environment. This test methodology is crucial for:
- The realistic service life prediction of components in hydrogen applications
- The evaluation of material behavior under dynamic load
- Minimizing risks due to hydrogen embrittlement
Through the targeted simulation of near-operational conditions, we provide you with reliable data for the safe selection and design of materials - in accordance with the requirements of tomorrow's hydrogen technology.
Fracture surface investigations
We combine scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDX) to analyze the microstructure and surface properties of your materials with the highest resolution. This high-precision examination method enables
- Identification of hydrogen-induced damage
- Clarification of causes and progression of damage
- Material characterization at micro and nano level
Our SEM/EDX analyses provide crucial information for failure analysis, quality assurance and the further development of hydrogen-resistant materials.
