Spring steel shall have excellent comprehensive properties

Spring steel shall have excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit and yield ratio), elastic reduction resistance (i.e. anti elastic degradation 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 accurate shape and size.
