>Explanation
>Cobalt-containing high-speed steel is relatively cheap and easy to process. Through appropriate heat treatment, high hardness can be obtained (～High red hardness (℃,～) and high wear resistance, toughness and flexural strength are not lower than ordinary high-speed steel, which can overcome early damage such as mold edge collapse and cracking.
> Steel, quite Regarding the problem of positioning the carbon content of steel in my country, the carbon content is positioned according to different product requirements, rather than uniformly positioning the carbon content within a certain fixed range. But no matter how it is positioned, the hardness must be guaranteed under normal heat treatment conditions, but too high carbon content will cause many negative effects.
>Hardness issue Hardness is the most intuitive technical indicator for evaluating high-speed steel cutting tools, but the most essential factor in heat treatment quality is the metallographic structure. Although so far, hardness is a more intuitive quantitative indicator for assessing the quality of heat treatment, but hardness is a surface phenomenon, and metallographic structure is the essential factor. Because it is just a piece of cake to achieve the above for super-hard high-speed steel, but it is quite difficult to achieve the ideal metallographic structure. Furthermore, there is no super hardness limit for any super-hard high-speed steel. High-speed steel cutting tools do not mean that the higher the hardness, the better. Being able to achieve high hardness and using high hardness are two completely different issues. For steel, it can be achieved with the correct heat treatment, but the tool has no practical value. For steel cutting tools, based on actual application experience and domestic and foreign data, it is best to control the hardness to a level that is more realistic.
>Standard comparison
>Factory state spheroidized annealing
>Characteristics and applications This steel is a high-speed steel containing tungsten and cobalt. Suitable for manufacturing wear-resistant and impact-resistant tools for powerful cutting, advanced punching dies, screw dies, tools that require toughness and complex shapes, reamers, milling cutters, drill bits, punches, etc.
>Forging temperature ℃
>Annealing temperature is heated to ℃, stay at this temperature for an hour, and let it gradually cool down in the furnace.
>The cooling medium is air cooling, oil, graded (℃)
>The optimal quenching temperature is between ℃.
>Typical application examples
>① Can be used to make various high-hardness and ultra-high-hardness saw blades, drill bits, taps, broaches, hobs and various milling cutters.
>②Cold forging dies, deep joining dies, cutting tools, etc.
③Recommended for cold stamping products industries such as watch case factories and screw factories.
Dalian Jingtai Industry and Trade Co., Ltd. specializes in the production of high-speed steel,,,,,,, and can develop new steel types according to customers' actual applications. Precision forged materials, hot rolled bars and cold drawn materials. The electroslag is redissolved and the carbides are small. Among them, the carbide particle size of the cold-drawn material was tested in the United States and reached 1 meter, which is much higher than the national standard. Strictly control the impact of impurity elements such as low magnification and microstructure on steel. The chemical composition follows the company's self-control standards and can reach around the middle line of the national standard. A quality guarantee is provided, the price is affordable, and the quality is guaranteed.
