Tempering
Description
Hardening is a process that considerably increases certain mechanical properties of steel.
These include hardness, tensile strength and yield strength.
It consists in cooling steel brought to a high temperature using a quenching medium (air, water, water-salt, forced air).
Revenue
Description
Tempering is a heat treatment mainly applied after hardening. It attenuates related defects and gives the steel an intermediate state between the quenched and annealed state.
Annealing
Description
Stress relief annealing is used to eliminate or reduce the level of residual stresses induced in assemblies by welding, machining or cold working operations, or even by previous heat treatment.
It can also be used to create a specific structure for subsequent heat treatment, or to create a structure suitable for machining.
Post-weld heat treatment is a process that refers to stress-relieving annealing and is required to remove residual stresses after the welds have been applied.
Nitriding Carbonitriding
Description
Gas nitriding is a modern thermochemical treatment performed in a mixture of nitrogen, hydrogen and, optionally, a carbonaceous gas. In this austenitic case-hardening process, similar to case-hardening but with the addition of nitrogen (via NH3 gas), the hardness of the steel is increased. wear resistance and surface hardness thanks to the creation of a hard surface layer.
Cementation
Description
Case hardening is the process of hardening the surface of a metal by infusing elements into the surface of the material to form a thin layer of a harder alloy. Combined with a subsequent hardening operation, case-hardening enables the properties of the component to be modified to suit the application.
