Case-hardening - Wikipedia
The advantage of this process is that it causes little distortion, so the part can be case-hardened after being quenched, tempered and machined. No quenching is done after nitriding. Cyaniding. Cyaniding is a case-hardening process that is fast and efficient; it is mainly used on low-carbon steels.Liquid Carburizing and Cyaniding of Steels - Heat Treating,,Liquid carburizing is a process used for case hardening steel or iron parts. The parts are held at a temperature above Ac1 in a molten salt that introduces carbon and nitrogen, or carbon alone, into the metal. Most liquid carburizing baths contain cyanide, whichInvestigation of Surface Hardness of Steels in Cyanide,,Investigation of Surface Hardness of Steels in Cyanide Salt Bath Heat Treatment Process S.P Ayodeji, T.E Abioye and S.O Olanrewaju Abstract - Carbonitriding of four types of steels, namely, low carbon steel (LCS), medium carbon steel (MCS), low alloy steel (LAS) and high alloy steel (HAS) was achieved using cyanide salt bath heat treatment process.
