Spring steel refers to steel that is specifically used to make springs and elastic elements due to its elasticity in the quenched and tempered state. The elasticity of steel depends on its ability to elastically deform, that is, within the specified range, the ability to elastically deform makes it withstand a certain load and does not appear permanently deformed after the load is removed. Spring steel should have excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), elastic resistance (i.e., elastic resistance to shrinkage, also known as anti-relaxation properties), fatigue properties, 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), precise shape and size.
