Product Description
Spring steel refers to steel specifically used for manufacturing springs and elastic components due to its elasticity in quenched and tempered states. The elasticity of steel depends on its ability to undergo elastic deformation within a specified range, which allows it to withstand a certain load without permanent deformation after the load is removed. Spring steel should have excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), anti elastic reduction performance (i.e. anti elastic reduction performance, also known as anti relaxation performance), fatigue performance, hardenability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). In order 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), and precise appearance and size.

In order 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), precise shape and size.
According to the GB/T 13304 "Classification of Steel" standard, spring steel belongs to mechanical structural steel based on its basic performance and usage characteristics; According to the quality level, it belongs to special quality steel, which requires strict control of quality and performance during the production process. According to Chinese customs, spring steel is a special type of steel, and the technical requirements for making spring steel are relatively high. Strong technology directly determines the quality.
