1. The DC*3 steel is improved on the base of SKD*1. The hardness after heat treatment is higher than that of SKD*1, reaching to ****3HRC if back fire in high temperature (******0°C); and the strength is also higher than that of SKD*1. 2. The flexibility is two times of SKD*1, more outstanding in cold working die steel, so there is little crack during manufacturing, which greatly improves service life. 3. The residual stress after linear cutting is greatly reduced through backfire in high temperature. Therefore, the crack and deforming of large dies and precision dies shall be restrained after linear cutting. 4. The performance of cutting is preceded to that of SDK*1 so that the service life is prolonged and the machining procedure is reduced. Uses: punching die, cold-work molding die, cold drawing die, molding roller, precision punching for linear cutting, as well as various pressing dies and plastic deformed tools. Characteristics: (1) good performance of being shaved and grinded; Both the properties of being shaved and grinded are more excellent than that of SKD*1, so the service life of machining tools is longer. (2) advantages of heat treatment The performance of fire quenching is more excellent than that of SKD*1, so the lack of hardness in vacuum heat treatment can be improved. (3) advantages of linear cutting Back fire in high temperature so that the residual stress can be eliminated, which prevents from chapping and deforming produced in linear cutting. (4) advantages of surface treatment The surface hardness after treated is higher than that of SKD*1, so the die? properties can be improved. (5) advantages of welding The temperature before and after heated is lower than that of SKD*1, so it is much easier to weld. Characteristics: use for cold working die steel, high hardness, high flexibility;
