DC-grade steel, spring steel, steels for hardening and tempering, and case-hardening steel are used in the production of flat wire products from Waelzholz. In addition to long lengths without weld seams, the shape of the edges can be freely designed as desired. This creates a wide range of variations for numerous different areas of application, such as for high-precision jigsaw blades.

Waelzholz’s hardened and tempered flat wire products stand out for their unparalleled durability while simultaneously maintaining bending uniformity. The reason for this is the particularly fine-grained and uniform microstructure, which is created via Waelzholz’s proprietary, patented conductive high-speed hardening and tempering process. In this process, the material is heated to temperatures well above 800 °C in a fraction of a second and then rapidly cooled again.
