Abstract

The invention discloses high-toughness high-speed steel and a preparation method thereof, and relates to the technical field of high-speed steel. According to the technical scheme, the high-toughness high-speed steel comprises the following raw materials by weight: 10-12 g of carbon, 14-16 g of silicon, 8-10 g of manganese, 9-10 g of chromium, 7-9 g of nickel, 4-6 g of vanadium, 6-8 g of nitrogen, 4-8 g of rhenium, 10-12 g of phosphorus, 5-7 g of sulfur, 4-8 g of antimony, 6-8 g of bismuth, 12-16 g of molybdenum, 1-2 g of tungsten, 12-14 g of cobalt, 8-12 g of rare earth and 30-40 g of iron, and the auxiliary materials by weight: 4-8 g of chromium carbide, 2-4 g of high manganese steel and 4-6 g of tungsten carbide. The high-toughness high-speed steel and the preparation method thereof have the beneficial effects that the carbon, the silicon, the manganese, the chromium, the nickel, the vanadium, the nitrogen, the rhenium, the phosphorus, the sulfur, the antimony, the bismuth, the molybdenum, the tungsten, the cobalt, the rare earth and the iron are selected as the raw materials, the chromium carbide, the high manganese steel and the tungsten carbide are selected as the auxiliary materials, and then proportioning is performed according to a certain proportion, so that the toughness and wear resistance of the high-speed steel are improved.

Description

technical field [0001] The invention relates to the technical field of high-speed steel, in particular to a high-toughness high-speed steel and a preparation method thereof. Background technique [0002] High-speed steel is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or front steel, commonly known as white steel, high-speed steel has good process performance, good strength and toughness, so it is mainly It is used to manufacture complex thin-edged and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies. [0003] The existing technology has the following disadvantages: most of the existing high-speed steels not only have poor toughness, but also poor wear resistance, which will affect the performance of high-speed steels. [0004] Therefore, it is necessary to invent a high-toughness high-speed steel and its preparation method. Contents of the invention ...
