Tensile tests

Five universal testing machines with load ranges from 2 kN to 1,000 kN are available for your tensile tests. Thus, it is possible to determine the characteristic values demanded in the standards, such as yield strength, tensile strength and elongation at fracture. Upon request, you receive the complete stress/strain curve. In our mechanical workshop, we can manufacture tensile test specimens in various formats, depending on the material and the requirement. Our spectrum of services extends from Z quality determination by establishing the area reduction at fracture via the testing of welded joints right up to tests on unmachined component specimens such as reinforcing steels and joints between them.

Hardness test

In addition to the common stationary hardness testing procedures according to Vickers, Brinell or Rockwell, we also offer you mobile hardness testing. This is sensible when your component is too large to move or must not be destroyed. Our experts come to you with their own devices and take measurements either with the UCI or TIV procedure. In this respect, we are also happy to advise you about what procedure is the most suitable for your testing task.

Bending tests

As far as welded joints are concerned, bending tests give a good impression of where the weak spots of a weld are. However, this test may be sensible for the base material too.

Bead bending tests

The bead bending test has been the subject of a lot of discussion but is still topical, e.g. in the case of bridges for railways. With this test, it is established to what extent a material is capable of stopping ongoing brittle cracks.

Notched-bar bend impact tests

Our pendulum impact tester with a working range up to 450 J can shatter notched-bar impact test specimens between the room temperature and ‑80°C and at ‑196°C. The toughness of your material is determined in this way. If you have only small material pieces, we can help you further with our pendulum impact tester for miniature specimens with working ranges up 25 J and 50 J.

Fracture tests

As far as welded joints are concerned, fracture tests are simple tests which can reliably reveal any defects in a weld. 

Special tests

If you now do not yet know how you can determine the properties of your component, get in touch with us! In many cases, we can build special test jigs ourselves. For example, we have developed a test jig for mechanical tests on delivery van doors.
