Abstract

The invention relates to high-toughness hot work die steel and a production method thereof and belongs to the field of alloy steel manufacture. The die steel comprises the components: 0.36-0.45% of C, 0.8-0.95% of Si, 0.7-0.8% of Mn, 4.8-5.5% of Cr, 1.3-1.8% of Mo, 0.8-1.0% of V, 0.3-0.6% of W, 0.4-0.5% of Ni, 0.1-0.2% of Co, 0.08-0.12% of Nb, 0.008-0.012% of RE, less than or equal to 0.003% of S, less than or equal to 0.025% of P and the balance Fe. The production method is implemented according to the following steps: (1) smelting; (2) electroslag remelting; (3) high-temperature homogenizing; (4) forging; (5) blank forging; (6) annealing treatment; and (7) quench tempering. The high-toughness hot work die steel is high in hardness, low in production cost, long in service life and relatively high in toughness, wear resistance and durability.

Description

technical field [0001] The invention relates to a strong toughness hot work die steel and a production method thereof, belonging to the technical field of alloy steel manufacturing technology. Background technique [0002] Tools and molds are known as the "mother of modern industry", which shows the importance and indelible contribution of tools and molds in modern industry. Among them, tool and mold steel is the most important part of molds, and it is also the most widely used material in mold materials. , is an important material carrier and technical foundation of the tool and mold manufacturing industry, and its variety, specification, and quality play a decisive role in the performance, service life and manufacturing cycle of the tool and mold. [0003] Steel is an extremely important metal material in economic construction. According to the chemical composition, it is divided into two categories: carbon steel (referred to as carbon steel) and alloy steel. Carbon stee...
