Why is high-speed steel called high-speed steel? Some people call it high-speed steel or white steel. However, most of us call it high-speed steel. Before the emergence of high-speed steel, carbon tool steel was generally used to make some tools and knives. The cutting speed is very low and cannot reach the point of cutting redness. Later, high-speed drying appeared. Its cutting speed increased productivity. The cutting temperature reached 500 to 600 degrees, and its hardness reached 60 degrees HRC or more. This is the main characteristic of high-speed steel, red hardness, and the red light can be seen when the environment is dark. Therefore, this revolutionary advancement was called high-speed steel, but later proved hard alloy or ceramic After the appearance of alloy tools, the cutting speed has gone up to a higher level, which is faster than that of high-speed steel.

There is another way of saying why high-speed steel is called high-speed steel. It is named after the material's processing speed. When there was no high-speed and high-speed before, some tools were made, such as turning tools and milling cutters. These are high-carbon steel T10A. It is made of material. At that time, T10A is due to a characteristic of this material. Here, its speed is relatively slow. It is usually less than ten meters per minute. After the emergence of high speed, its cutting speed can reach every minute. 30 meters, so it was named high-speed steel according to a feature of high-speed cutting ability at that time, because its speed is relatively fast, so it is called high-speed steel
