Automotive Retaining Spring clip sheet metal stamping

Spring steel should have excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), resistance to elastic decline (namely, resistance to elasticity decline, also known as relaxation), fatigue property, hardenability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, 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 decarbonization), precise shape and size.
