High-Speed Hardening & Tempering: Flat Wire & Profiles with Homogeneous Microstructures & Residue-Free Surfaces

By Waelzholz North America, LLC

When homogeneous materials with a residue-free surface and unparalleled forming properties are required, Waelzholz’s patented high-speed hardening and tempering method is the solution of choice.

The process of heating the steel strip to well over 800°C in a few fractions of a second and then cooling it just as quickly produces an extremely fine-grained and homogeneous martensite microstructure.

This is how we manufacture flat wire products and profiles made of wire with above-average bending uniformity and residue-free surfaces such as those required for a variety of applications in the automotive industry.
