SKD11 is a high wear resistance and toughness general cold die steel, high carbon high chromium alloy tool steel and vacuum degassing refining steel, steel purity, with a good quenching, quenching deformation of small good quenching. The steel can be processed by ball annealing and softening, and can be processed well, fine and uniform carbide particles are not required to be worried about the quenching cracking and strengthening elements molybdenum and vanadium.
SKD11 is, Hitachi and Datong steel mills have production, Hitachi SKD11 production of SLD goods called (the latest improved version called SLD-MAGIC), Datong steel mill product name is DC11. Both in the mainland have set up factories in the industry's most famous, the price is also the highest. This steel is a kind of cold working die steel in the wide application of the world. The electric furnace smelting and the electroslag remelting, high purity, better toughness, uniform structure, has good high temperature strength, toughness and anti fatigue properties at high temperature, withstand sudden changes of temperature.
High hardness, high wear resistant eutectic carbide uniform, good toughness, not easy to crack, after quenching hardness >62HRC.
