Problems solved by technology

[0003] When used as a cutting blade and drill material, due to the characteristics of long cutting and drilling, the temperature of the blade or drill is too high. When cutting and drilling at high temperature, its hardness and strength drop sharply, and it is easy to produce nodules and crescent wear. At the same time Seriously affect the wear resistance and service life of cutting tools and drill materials

Abstract

The invention relates to a high-strength alloy material. The high-strength alloy material comprises the following components of, in parts by weight, 0.5-1 part of manganese, 2-4 parts of molybdenum, 1-2 parts of chromium, 5-7 parts of nickel, 11-13 parts of carbon, 15-20 parts of iron, 12-15 parts of silicate and 7-10 parts of barium hydroxide. The method has the beneficial effects that the wear resistance is better; and the hardness of the alloy is improved; the high-temperature strength is better.

Description

technical field [0001] The invention belongs to the technical field of alloys, in particular to a high-strength alloy material. Background technique [0002] As a new type of engineering material, steel-bonded cemented carbide has excellent properties between tool steel and cemented carbide, as well as machinable and good heat treatment characteristics, making its application in the manufacturing industry more and more popular among material workers. focus on. [0003] When used as a cutting blade and drill material, due to the characteristics of long cutting and drilling, the temperature of the blade or drill is too high. When cutting and drilling at high temperature, its hardness and strength drop sharply, and it is easy to produce nodules and crescent wear. At the same time Seriously affected the wear resistance and service life of cutting tools and drill bit materials. Contents of the invention [0004] In order to solve the above problems, the present invention adop...
