Abstract

The invention discloses a die steel material as well as a preparation method and application thereof, wherein the die steel material comprises the following elementary compositions in percentage by mass: 0.38-0.48% of C, 3.0-3.5% of Cr, 2.5-3% of Mo, 1.2-1.5% of V, 0.8-1.2% of Si, less than or equal to 0.65% of Mn, 0.02% of P, 0.02% of S, 1.8-2.4% of W and the balance of Fe. The die steel material disclosed by the invention not only can keep high strength, high thermal stability and high cold and hot fatigue resistance, but also can keep relatively high toughness and plasticity, so that the die steel material has good heat treatment and processing properties; and industrial and living wastes including waste steel and the like can be used for manufacturing mold materials, so that the production cost can be significantly reduced, and the recycling of waste resources can be realized, thereby achieving very ideal comprehensive benefits.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a mold steel material and its preparation method and application. Background technique [0002] With the rapid development of my country's manufacturing industry, especially the rapid growth of the automobile manufacturing industry, my country's valve manufacturing industry has already occupied an important proportion in the world. However, in the prior art, the powder metallurgy molds used in the valve production process have disadvantages such as high price, irreparability, and low adoption rate. In addition, the service life of the mold is short and the application efficiency is not high. [0003] Therefore, the current mold materials and their preparation techniques need to be further improved. Contents of the invention [0004] In order to solve the above technical problems, in one aspect, the invention discloses a mold steel material, in another aspect,...
