D2 alloy tool steel is a highly wear-resistant micro-deformation cold work die steel, which is melted using the patented vacuum arc technology of Fincola in the United States. The carbon content is as high as 1.55, the chromium content is 12, and the hardness after heat treatment can reach 60HRC. D2 cold work alloy tool steel imported from the United States can be used to manufacture cold work molds with large cross-sections, complex shapes, large impact forces, and high wear resistance. Such as silicon steel sheet punching dies, cold cutting scissors, trimming dies, hardware stamping dies, drawing dies, stainless steel sheet punching dies, high hardness punching dies, wire rolling dies, hardware parts production and machinery manufacturing, etc.
SKD11 is Japan’s standard brand of cold work die steel. Hitachi’s trade name is SLD die steel (the latest improved version is called SLD-MAGIC), and Datong Steel’s trade name is DC11 die steel. Neither of them has factories in mainland China. They are the most well-known in the industry and have high prices. This steel is an air-cooled hardening cold work die steel that is widely used internationally. Smelted in an electric furnace and re-dissolved by electroslag, it has high purity, better toughness, uniform structure, good high-temperature strength, toughness and high-temperature fatigue resistance, and can withstand sudden changes in temperature.
