Nanjing Huaxin Machinery Tool Manufacturing Co., Ltd. is a professional manufacturer of mechanical cutting tools. At present, the granulator blades are mainly made of SKH9 high-speed steel and ceramics. Many people do not know much about SKH9 high-speed steel. Huaxin shares with you the basic knowledge about SKH9 high speed steel：
SKH-9 was originally a tungsten-molybdenum-based high-speed steel from Japan. The alloy composition is W6Mo5Cr4V2. Similar mold steel models include SKH-51, M2, etc., which are standard by the Japanese Ministry of Industry. Due to its high market reputation, it has now become synonymous with the industry. .
The current SKH-9 high-speed steel generally refers to W6Mo5Cr4V2 high-speed steel. SKH-9 high speed steel has fine and uniform carbides, good impact toughness, good wear resistance, good high temperature softening performance, can resist 600 ℃ high temperature and is not easy to soften, hardness HRC62-64, wear resistance is colder than high carbon high chromium type The die steel is increased by 2 times, and the cracking resistance is also increased by 1.5 times, but the heat treatment cost is high, and the heat treatment process is not easy to control.
SKH-9 high-speed steel is a universal high-speed steel in the world, and it is the best-selling die steel among all high-speed steels. Forging is 1.100~900℃, annealing is heating to 800-850℃, quenching is preheating to 550-600℃.
When you understand the advantages and characteristics of skh9 high-speed steel, you will understand why we produce skh9 material granulator blades.
