The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, A573 Grade 65 steel sections, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.
