In this paper, the influence of tempering temperature on the magnetic memory amplitude of 2Cr13 steel was investigated. Its mechanical properties and magnetic performance were evaluated based on the magnetic memory technique. The magnetic memory signal at each stage of stretching the tempered steel was acquired. The variation mechanism of magnetic memory signals during stretching was discussed, and a technique was proposed to evaluate the tensile damage based on magnetic memory. The results revealed that the magnetic memory technique, as a novel nondestructive testing technique, can quickly, efficiently, and extensively evaluate the properties of tempered steel and additionally predict the tempering temperature and degree of tensile damage.
