Can 440C stainless steel wire make cold bending slingshot?
Spring steel is the steel used to make springs and elastic elements because of the elasticity in quenching and tempering. The elasticity of a steel depends on its ability to deform elastically, i.e., within a given range, the ability to deform elastically so that it is subjected to a certain load, without permanent deformation after removal of the load.
Spring steel has excellent comprehensive properties, such as mechanical properties (especially the elastic limit and ultimate strength, yield ratio), ballistic performance reduction (i.e. anti sagging performance, also known as anti relaxation properties), fatigue performance, hardenability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance and corrosion resistance etc.). To meet the above performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), accurate shape and size.
