The current standard for quenching and tempering of carbon steel strip and stainless chromium steel is to use either a lead-bismuth-based molten metal bath or hydrogen for quenching.

We have combined the advantages of these two technologies and developed a worldwide unique, lead-free quenching system for a wide range of sizes. This is our unique selling point.

This innovative technology has been used by Risse + Wilke for many years, especially for applications with highest demands on technological properties, microstructure, and shape tolerances, and has been continuously developed. With this lead-free process we achieve a 50% improvement in flatness compared to conventional lead bath quenching and can also lead-free quench and temper steel strip up to 5 mm thickness.

A new approach to quenching and tempering.
