Materials Testing: High performance for internal and external customers
As an elementary cornerstone of the innovation area at thyssenkrupp Steel Europe, Materials Testing makes essential contributions to ensuring product quality/development with a comprehensive range of steel-typical testing capabilities and methods. We also offer tailored material solutions and services outside our own organization.
In all work relating to the testing and analysis of materials and surfaces, the interplay of specialist skills, technical capabilities and know-how forms the foundation for delivering high-quality services.

Services for internal and external customers
We offer consulting and support in the analysis of materials and production processes according to your individual requirements:
Drop tower test
In drop tests with drop heights of up to 10 meters and drop speeds of up to 50 km/h, FE simulations are validated and the energy absorption behavior of components and materials is investigated.
Rotating wheel abrasive wear tests according to ASTM and wear pot tests can be performed to determine the wear behavior of metallic materials.
Determination of the forming limit curve (FLC) according to DIN EN ISO 12004-2 and determination of the biaxial stress-strain curve (bulge test) according to DIN EN ISO 16808 with optical measuring systems as well as performance of deep drawing cup tests and Erichsen cupping tests.
High speed tensile tests
Determination of flow curves at high strain rates according to SEP 1230 which are required for the numerical simulation of crash loads.
High cycle fatigue tests
Tests under oscillating stress to determine material-specific fatigue properties and the determination of S-N diagrams
Standard tests such as tensile tests, bending tests, end quench tests, notched-bar impact-bending tests, hole expansion capacity and hardness tests according to the current standards complete the range of mechanical-technological materials testing services
Surface analysis and corrosion
Salt spray tests according to DIN EN ISO 9227 or change tests according to DIN 55635 (VDA 233-102) are carried out in partly walk-in corrosion chambers. Outdoor weathering tests are also possible.
Paint adhesion test
For the assessment of the bond strength, methods such as the stone impact test according to DIN EN ISO 20567, cross-cut test according to DIN EN ISO2409 and conical mandrel bending test according to DIN EN ISO 6860 are used.
In the step-load test according to VDA 283-201, an increasing mechanical load is applied in a corrosive environment to simulate exemplary conditions during vehicle production and vehicle use.
Wet chemical analysis
Determination of the chemical composition of coatings by ICP spectrometry and gravimetric determination of the coating weight for the analysis of metallic coatings and post-treatments
Glow discharge optical emission spectroscopy GDOES
Analysis of the layer structure of metallic and non-metallic coatings, as well as the composition of the underlying base material in the form of a quantitative depth profile
Metallurgy and metallography
Microrange analyses with electron beam microprobe (EPMA/ESMA)
Wavelength dispersive X-ray spectroscopy (WDX) can be used to quantitatively analyze element distributions on two-dimensional surfaces and display them in the form of a color-coded element map (according to ISO 11938). Fields of application among others: Tests on slabs, hot strip, cold strip and surface-finished products.
X-ray diffraction on crystalline powders and solids
We offer the following procedures, among others: Qualitative phase analysis on crystalline powders and solids, quantitative residual quartz determination in silica bricks, quantitative residual austenite determination in ferritic steels, texture analysis
Transmission electron microscopy (TEM)
Transmission electron microscopy on carbon extraction replicas allows us to characterize precipitation states on low/microalloyed ferritic steels. Precipitates > 2 nm can be imaged in correlation to the microstructure and subsequently analyzed by EDX with respect to their chemical composition.
