Aka Wind steel or steel front, also known as white steel. Means that even if the cooling time of quenching can be cured in air, and very sharp. It is a component of a complex of steel, comprising forming elements tungsten, molybdenum, chromium, vanadium, cobalt carbide. The total amount of alloying elements of about 10 to 25%. It produces fever cases in high-speed cutting (about 500 ℃) still maintain high hardness, HRC can in 60 or more. This is the most important characteristic of high speed steel - red hardness. And the carbon tool steel after quenching and tempering, at room temperature, although the high hardness, but when the temperature is higher than 200 ℃, the hardness will be decreased drastically, 500 ℃ hardness in the annealed condition and has been reduced to a similar extent completely lost the ability to cut the metal, which limits the production of carbon tool steel cutting tools. The high-speed steel due to good red hardness, to make up for the shortcomings deadly carbon tool steel, can be used to manufacture cutting tools.
