  • Edge crack sensitivity test, e.g. hole expanding test according to ISO 16630

Strain-controlled Wöhler fatigue tests on base materials according to SEP1240

We analyze fatigue strength in elastic-plastic cyclic deformation, whereby the size of the residual strains serves as a measure of the material damage. We do this with a strain-controlled Wöhler fatigue test.

As failure criterion, the number of cycles NA at crack formation is used in lieu of the number of cycles to failure NB. This test supplies the characteristic values of the material for the local calculation concept in the service life calculation of components.

Strain rate-dependent tensile tests on base materials according to SEP1230

With strain rate-dependent tensile tests, mechanical-technological properties such as strain limit, tensile strength and elastic modulus are characterized using stress-strain curves at different loading speeds. The measured values are recorded locally on the specimen by means of glued-on strain gages for precise force measurement as well as by an optical displacement measurement system for exact deformation measurement.


Creep tests

We are the experts!

For the reliable evaluation of materials, we conduct creep tests with run times of up to 100,000 hours or more. The test results serve as a basis for the qualification of steel products, the analysis of the remaining service life of components in existing power stations and chemical plants, and the standardization of creep-resistant steels. We test materials in the as-delivered condition as well as components after having been subjected to operating loads. Along with the testing of rolled, forged and cast products, we also test welding filler materials and welds. In the analysis of creep results, we offer you scientific support.

  • 220 individual testing stations with test temperatures ranging from 400 °C to 950 °C
  • Test load up to 40 kN
  • Uninterrupted creep tests according to DIN EN ISO 204 in single-specimen ovens
  • Continuous strain measurement for the determination of creep in materials
  • Short and long-term testing with run times of up to 100,000 hours or more
  • Creep tests under controlled water vapor atmosphere as well as under cyclical load and variable temperature control
