Overview of SKH40 high-carbon high-speed steel.
SKH40 is a high-carbon high-speed steel that is widely used in the field of cutting tools and heavy machinery manufacturing due to its excellent hardness and wear resistance. This steel is made by having a carbon content of 07% of ordinary high-speed steel is made of tungsten, chromium, vanadium and other alloying elements, which has excellent high-temperature hardness and red hardness.
SKH40 high-carbon high-speed steel has a carbon content of up to 07%, giving it a very high hardness, usually between HRC63-66. At the same time, the wear resistance of the steel is excellent, mainly due to the uniform distribution of alloying elements inside and the stability of high-temperature tempering. Compared with other high-carbon high-speed steels, SKH40 has better toughness and is not easy to crack or chip.
In the field of cutting tools, the hardness, wear resistance and toughness of SKH40 high-carbon high-speed steel make it an ideal material for manufacturing cutting tools such as milling cutters, drills, taps, etc. These tools have high cutting speeds and cutting life when cutting steel, cast iron and non-ferrous metals, resulting in increased productivity and machining quality.
In addition, SKH40 high-carbon high-speed steel is also widely used in the field of heavy machinery manufacturing, such as the manufacture of consumable parts for excavators, crushers, rolling mills and other equipment. These consumables need to operate for long periods of time under extreme operating conditions, so they need to have high hardness, high wear resistance and good toughness. SKH40 high-carbon high-speed steel is able to meet these requirements, extend equipment life and reduce maintenance costs.
In conclusion, SKH40 high-carbon high-speed steel has become one of the preferred materials in the field of cutting tools and heavy machinery manufacturing due to its excellent hardness and wear resistance, good toughness and high-temperature tempering stability. In the future, with the continuous development of industrial technology and the expansion of application fields, SKH40 high-carbon high-speed steel will continue to play an important role.
