For components that must withstand exceptionally high loads, high-strength materials are used. Typical applications include:

• High-strength steels
• Springs and stabilizers
• Wires for springs and stabilizers
• High-purity steel

Fatigue Strength of Components with High-Strength Materials

The service life of such components is determined through rotary bending tests. Typical applications include:

• Comparing the fatigue strength before the raw material is processed into the final product
• Material optimization (e.g. type of material, heat treatment, shot peening parameters, reduction of scatter)
• Detecting cracks, inclusions or similar defects in the material to assess material quality
• Evaluating surface quality

Advantages of the IABG rotating bending test benches

When using high-strength materials, the service life must consider not only the material's fatigue strength but also surface defects and material volume inconsistencies.

The IABG rotary bending test benches allow for a time- and cost-efficient determination of the fatigue strength of high-strength materials used for the production of springs and stabilizers, resulting in these advantages:

• No clamping of round bars required due to special bearings
• High test frequencies
• Large and thus representative material volume
• Short installation and changeover times
• Reliability and low maintenance requirements
