A process in which an iron base alloy is heated in contact with a cyanide salt so that the surface absorbs carbon and nitrogen. Cyaniding is followed by quenching and tempering to produce a case with abination of hardness and toughness.
Heat treatment process has emerged as a robust scheme to incorporate variations in the microstructural, physical and mechanical properties of steel materials. Since, heat treatment is the process
Heat Treatment Processes Hardening Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
List the various stages of a heat treatment process. Stage 1: Heating a metal/alloy beyond the critical temperature. Stage 2: Holding at that temperature for a sufficient period of time to allow necessary changes to occur. Stage 3: Cooling the metal/alloy i.e., quenching at a rate necessary to obtain the desired properties. That is, cooling at a rate necessary to obtain the desired

While tempering, enhances ductility or should i say improves formability, cyaniding improves skin hardness or
Annealing is a heat treatment process which involves heating and cooling. The process is normally used for the softening of steel. The term also refers to treatments intended to alter the mechanical or the physical properties, to produce a definite microstructure, or to remove gases.

Flame or induction hardening are processes in which the surface of the steel is heated very rapidly to high temperatures by direct application of an oxy gas flame, or by induction heating then cooled rapidly, generally using water this creates a case of martensite on the surface. A carbon content of 0.30.6 wt C is needed for this type of hardening.
Typical uses are for the shackle of a lock, where the outer layer is hardened to be file resistant,
