DC53 Cr8Mo1VSi High Strength Toughness Universal Cold Work Mold Steel
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.
Cold work DC53 tool steel overcomes the insufficient of SKD11 high temperature tempering hardness and toughness of weakness, DC53 tool steel will fully replace SKD11 tool steel in the field of general and precision mould . Its toughness is 2 times of SKD11, DC53 toughness is more prominent in the cold work die. Made of DC53 tools steel rarely appear crack and craze, greatly improving the service life.
The DC53 tool steel has a uniform distribution of fine carbides. It has great galling and wear and fatigue resistance. It has also a High temper resistance to support PVD & nitride surface treatments. And it has Machining and grinding properties are superior to most other tool steels.
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.
