Abstract

The invention discloses die steel with high performance and a preparation method of the die steel. The die steel comprises the components of, by weight, 0.8-1.5% of C, 1.0-2.0% of Si, 4.5-5% of Cr, 0.5-1.0% of Mn, 0.2-0.6% of Mo, 0.02-0.1% of Al, 0-0.05% of MgO, 0.01-0.05% of CaF2, 0.02-0.08% of CaC2, and the balance Fe. The preparation method comprises the steps that (1) the components are mixedaccording to a formula, and heated and fused under the inert gas atmosphere, then CaF2, MgO and CaC2 are sprayed into the components, the components continue to be fused, and molten steel is collected; (2) the molten steel is poured into a part, and the part is heated and temperature rises; and (3) the product obtained in the step (2) is forged, quenched and tempered. The die steel prepared by themethod is low in inclusion content, and the properties like impact toughness and shock strength are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of die steel preparation, and in particular relates to a high-performance die steel and a preparation method thereof. Background technique [0002] my country is the largest steel producing country in the world. In 2015, it produced about 800 million tons of steel and exported 110 million tons of steel products. However, there is still a big gap between the production technology of high-end steel materials and advanced countries in the world. Many special materials must rely on imports. , In 2015, it imported 3.9 million tons of high-end special materials, including about 200,000 tons of tool and die steel, worth about 20 billion yuan. [0003] Mold is the mother of industrial manufacturing. 60% of industrial products need to use molds to produce various products. In 2015, the output value of mold industry has exceeded 2 trillion yuan. The annual consumption of various die steels is about 10 million tons. A...
