Lead-free QT

Innovative process for lead-free quenching and tempering

Risse + Wilke Cold Rolled Steel Inc. has developed a worldwide unique lead-free quenching system for a wide range of sizes.  

This innovative technology has been used by Risse + Wilke for many years, especially for applications with highest demands on technological properties, micro- structure, 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.
