DC53 is a new type of cold working die steel modified from SKD11 by datong special steel, whose technical specification is contained in Japanese industrial standard (JIS) G4404.It overcomes SKD11 high temperature temper hardness and toughness weakness, will be in the general and precision die field comprehensive replacement of SKD11 high strength and toughness universal cold die steel.
Under proper heat treatment, the strength and toughness are excellent, and the high-temperature temper hardness can reach 62~63HRC.The toughness of DC53 is more prominent in cold die steel, and few cracks and cracks appear in tools made with DC53, which greatly improves the service life.The residual stress after wire cutting is reduced by high-temperature tempering.As a result, cracks and deformation of large molds and precision molds are suppressed after linear cutting.
