The paper objective is to develop a domestic quenching oil for hardening spring clips. The study results of the effect of quenching liquid cooling properties on 40C2 steel hardness are presented. Domestic quenching oil Rosoil-277, an analog of the imported oil Isorapid 277 (PETROFER Germany) is made - for quenching rail clips. The tests were carried out at the installation to determine the cooling characteristics of technological and quenching media. A water-polymer quenching liquid is selected as a substitute for quenching oil. The results of hardness measurements on 40C2 steel workpieces showed that quenching in Rosoil-52 water-polymer quenching liquid gives higher hardness values compared with quenching in Rosoil-277 oil.
