spring steel wire is to study the development of new kinds of steel. We must first understand the characteristics of various alloying elements, and design steel chemical composition scientifically.
(1) Carbon
Carbon is the most important element of spring steel wire. Carbon content plays a vital role on the performance of spring steel. In order to ensure sufficient strength of spring steel wire, and its hardness, flexibility and fatigue life, steel must have a very high carbon content, so the carbon content of alloy spring steel wire is generally higher than the alloy steel.
(2) Silicon
the silicon content in spring steel wire is more than 1wt%, even up to 3wt%. The main purpose of adding silicon is to improve strength, flexibility and tempering stability of spring steel wire.
(3) Manganese
Manganese is also commonly used in the spring steel wire. Manganese helps eliminate the harmful effects of sulfur and is beneficial to deoxidize. Manganese significantly increased hardenability, improve heat treatment performance, thereby enhancing the strength and hardness of steel.
(4) Chromium
chromium's highlight advantage is that it is not easy to promote decarburization of spring steel wire and can significantly improve the hardenability of steel.

(5) Other alloying elements
Recent studies of micro alloying elements of spring steel wire attached great importance. The most involved trace element is boron, which is an element of improving hardenability. It can also improve the plasticity, toughness and resistance to elastic weakening.
