The heat treatment of steel after its formation is rather important.
The treatment of steel is now an elaborate science of its own, and it is, of course, closely connected with the contents of the steel. The heating and the quenching are designed to bring about the arrangement of the crystalline structure in the desired way, to give the required properties. For example, steels containing a high percentage of carbon may be quenched after being heated to a high temperature to make them hard, and then moderately tempered to restore toughness.
No steel is used today that has not been tested. The simplest examinations are those мейд with magnifying glass or a microscope.
Spectroscopic or chemical analysis, X-ray examination, and magnetic or electrical tests may be applied. Specimens are also subjected to physical tests for toughness, strength, and hardness.
