As a general-purpose steel, spring steel is used to make springs for automobile and industrial suspensions. Generally, low-alloy manganese and medium/high carbon steels with very high yield strength are used. This allows objects made of spring steel to be prominent In the case of deflection or distortion, it returns to its original shape. For springs subjected to fatigue loads, high requirements are placed on surface finish and internal cleanliness (limiting the number of non-metallic inclusions). 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.
