Abstract

The main types of currently used free-machining steels, including corrosion-resistance free-machining steels, are observed. The chemical composition of corrosion-resistant free-cutting steel has been developed. The influence of various quenching and tempering temperatures on the microstructure and properties of corrosion-resistant free-cutting steel has been investigated. The results on the machinability of steel with the selected chemical composition and its heat treatment mode, ensuring an increase in cutting speed and tool life, are presented.
