Operational requirements
To perform their operational functions, the spring and spring actuators must have:
- Increased elasticity;
- Sufficient plasticity during processing;
- Stability against alternating loads.

The urgency of heat treatment
Obtaining the necessary set of properties of spring and spring steel is possible only after heat treatment. Given that all the steels of this group are high-carbon and have a sorbit / troostite structure, the heat treatment mode should not lead to internal stresses and prevent spontaneous aging of the products under load (prevent creep). The initial state of these steels is ferrite in the mixture with carbides. The first component determines the plasticity of spring-spring steels, and the second — the brittleness. To give the equilibrium structure to the bed structure, it is quickly heated to temperatures above the formation of a solid solution of carbon in α-iron (700… 720 ° С), and then moderately quickly cooled in oil so as not to create internal structural stresses. It is under such conditions of heat treatment that steel gets an equilibrium crystal structure. In addition, it can be improved by annealing, but at the same time the initial hardness falls, which, in turn, will reduce the longevity of the part.
