Spring steel high hardness and high wear-resistant spring steel

Spring steel refers to special alloy steel for manufacturing various springs and other elastic elements. According to performance requirements and operating conditions, it can be divided into ordinary alloy spring steel and special alloy spring steel. Spring steel has excellent comprehensive properties, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), precise shape and size. Spring steel refers to steel specially used to manufacture springs and elastic elements due to its elasticity in the quenched and tempered state. The elasticity of steel depends on its elastic deformation ability, that is, within the specified range, the elastic deformation ability makes it bear a certain load, and no permanent deformation occurs after the load is removed. Spring steel should have excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), elastic reduction performance (that is, elastic reduction resistance, also known as relaxation resistance), fatigue performance, hardenability , Physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.).
