Spring steel is steel that is specially used to make springs and elastic elements due to elasticity in quenching and tempering conditions. The elasticity of the steel depends on the ability of its elastic deformation, that is within the specified range, the ability of elastic deformation to withstand a certain load, after the removal of the load does not appear permanent deformation.

Spring steel should have excellent overall performance, such as mechanical properties (especially the elastic limit, strength limit, yield ratio), the impact of anti-performance (that is, anti-elastic performance, also known as anti-relaxation performance), fatigue properties, , Physical and chemical properties (heat, low temperature, anti-oxidation, corrosion resistance, etc.). In order to meet these performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), precise shape and size.

According to GB / T13304 "steel classification" standard, according to the basic performance and characteristics of the use of a spring steel is a mechanical structure of steel; in accordance with the quality level, are special quality steel, that is, in the production process requires special strict control of quality and performance of steel. In accordance with Chinese habits, spring steel is a special steel, spring steel production when the technical requirements are relatively high, excellent technology directly determine the level of quality.
