Not all high-strength materials are created equal – if you define and select materials solely on the basis of the mechanical properties of yield strength, tensile strength, and elongation, you’ll miss out on the chance to obtain the material with the best overall potential for the desired purpose. After all, Waelzholz offers no less than six different material groups that all fall into the high-strength category. Yet their other properties that are relevant to further processing and the final application are all very different. This is where customers find a truly customized solution for their unique requirements.
When a steel grade has a yield strength of more than 800 MPa, it is referred to as high-strength steel. Some applications, for example clutch plates used in automotive manufacturing, require yield strengths of up to 1,200 MPa, which Waelzholz’s high-performance RAWAEL© material achieves. But the majority of applications across the high-strength spectrum lie in a range of yield strengths that are covered by very different materials, however. At Waelzholz, customers can choose from six different material groups (Figure 1). Each offers different capabilities, for example with respect to weldability, spring properties, isotropy, and longitudinal and transverse bendability. The advantage is that, in addition to strength, these properties can be included in the calculation to determine the best material for the application in the respective customer project. As a result, the customer receives a highly customized material solution.
