Our bainitic hardened and tempered PT-strip (pre-tempered) has an ideal combination of pre-adjusted component strength, good formability and good bendability. It has optimal spring properties, even for dynamic, highly-stressed parts. It is used, for example, in connecting, fastening and spring clips in mounting applications.
Waelzholz owns special, high-performance machinery for bainitic hardening and tempering and is specialized in the production of PT-strip. This is how we guarantee absolutely homogeneous processing and forming properties as well as constant mechanical-technological characteristic values. Our customers benefit from the high- reproducibility of their components, as this translates to process stability. The greatest advantage of using PT-strip is the absence of time-consuming and expensive piece hardening. Stamped, bent and formed parts can be manufactured in one single step without any deforming or heat cracks. The result is optimal processing efficiency.
