Heat Treatment

Metal Heat Treatment

Heat treating is a process used to change the structure and composition of a material. SGS MSi uses heat treatment to alter the material metallurgically in order to observe and test its characteristics.

The process of heat treatment involves the raising of a materials temperature to a specific point that allows a change in the material to occur. When this level is reached, the material is cooled in a specified manner. Examples of these methods are oil, air and water cooling. These cooling methods will yield several different results based on the materials specification requirements. The need for a softer or harder material can be achieved by heat treating the material and cooling it to a desired hardness. The material may need to be harder on the surface and softer in the core. This is called case hardening.

Heat treatment has a number of different techniques for changing a structure of metal. Some of these techniques are quenching (oil, water, air, bismuth). Another method is annealing, where the material is heat treated to become more workable.
