Cyaniding. Cyanide may also be used to case harden the steel. It is used to give a very thin but hard outer case. Cyaniding is a case hardening process in which both C and N 2 in form of cyaniding salt are added to surface of low and medium carbon steel. Sodium cyanide or potassium cyanide may be used as the hardening medium.

What is Heat Treatment Process in Steel? SMLease Design

The Tempering heat treatment process involves reheating martensitic steel at a temperature below its critical temperature ( or eutectoid temperature ) and then cooling it slowly. Tempering of hardened or normalized steel improves material dimensional stability, toughness and reduces hardness by relieving stress produced during quenching.
