​​​High Tech Testing for High Performance Materials

In our ISO 17025 accredited and NADCAP-MTL certified test laboratories, approx. 500,000 test orders are carried out annually according to 180 different accredited test methods. The central database for recording all test data, LISA-LIMS, has been in highly reliable use since 2003.

In certification, approx. 50,000 certificates are issued annually on the basis of the test results from the production and the testing laboratories.

Chemistry labs

Our modern chemistry labs provide the production facilities with important information for process control, product certification, and environmental monitoring.
To determine the composition of metal and nonmetal materials such as steel, nonferrous alloys, raw materials, and ancillary products from special steel production, we use inorganic chemical analysis methods

Process analysis and solids analysis

Tasks: Analysis of solid samples with the goal of shorter response times with maximum precision and accuracy.
Methods: X-ray and spark spectrometry, as well as combustion analysis and melt extraction.

Wet chemistry

Tasks: Trace analysis for process samples and identification of the main and secondary components for difficult matrices, provision of certified calibration samples and reference materials for solids analysis, specialized raw-material and waste analyses, and analysis of environmentally relevant samples.
Methods: Classical wet-chemistry analysis methods combined with cutting-edge optical spectrometry, mass spectrometry, and chromatography.

Corrosion testing

Tasks: Corrosion testing of steels and alloys.
Methods: Various methods conforming to international standards and specific regulations for testing resistance to general erosive corrosion, intercrystalline corrosion, stress fracture corrosion, pitting corrosion – including electrochemical test methods.

Mechanical and technological materials testing

Tasks: Determining mechanical parameters.
Methods: Performing tensile, hot-tensile, notched-bar impact, and stress rupture testing, as well as hardness testing per Brinell, Rockwell, and Vickers on steel and nonferrous alloys in compliance with international standards and regulations.


Tasks: Determining microstructure parameters of samples and components—including sample preparation, etching, and photodocumentation—according to inspection standards and customer specifications.
Methods: Determining structure, grain size, and purity level, decarburization, etc.

Heat treatment

Tasks: Heat treatment of samples and components according to the requirements of our customers.
Methods: Heating in lab furnaces monitored by the system, in both air and vacuum, supplementary salt baths and sub-zero treatments for residual austenite transformation. Water and oil are available as quenching media.

Metallurgical & physical lab

Tasks: Performing hot-forming simulations, differential thermal analyses and dilatometric testing, heat-treatment and forming simulations, creating TTT and TTA charts, sub-zero simulations, determining linear expansion coefficients, and investigating recrystallization and precipitation processes.
Methods: Material and damage analyses of microstructure samples and fractures, as well as qualitative analysis of nonmetallic inclusions using scanning electron microscopy, measuring physical properties of materials such as testing magnetically soft materials, stress and strain analyses using strain gages, and X-ray diffraction analyses (residual austenite, phase analysis).
