Free Cutting Steels without Plumb

 


For many decades free cutting steels, case-hardened steels and quenched and tempered steels were added by small quantities of plump to improve the machinability. Plump leads among other things to the formation of lubricating intermediate layers, which cause a decrease of the tool wear and the total force. Further the chip breakage improves due to the embrittling effect by alloying of plump. The goal of this project was to find out alternatives of plump for improving the machinability free cutting steels and to evaluate the machinability of modified steels.
