History of spring steels
Ancient Greek engineer Ktesibius invented a method of increasing the elasticity of bronze. After casting, the bronze was forged with the blows of a hand hammer, thus obtaining flat springs. The first spring alloys were obtained in England in the XVIII century. The English watchmakers have found that additions to conventional carbon and silicon steels not only increase the hardness of the metal, but also increase elasticity. At the same time it was established that the spring properties of steel rolled steel after hot forging with a hammer. At the end of the 18th century, the Englishman J. Brahm invented a spring-coiling machine. Later, the technology of quenching of spring steels was worked out, so that the final products were simultaneously strong, durable and resilient.

History of spring steels
Firstly, ordinary steel strips were used to make the springs. However, such springs did not last long. Addition to the chemical composition of carbon and silicon revealed an increase in the elastic properties of the material and an increase in its strength, especially under dynamic loads. Unlike springs, the springs were made of strip steel, which was then heat treated. And already in the twentieth century they learned to alloy the spring alloys with vanadium, chrome and other elements, which provided the spring with increased durability and durability.
