The difference between carbide steel and high speed steel
Hardness and wear resistance: Carbide is harder than high-speed steel and has greater wear resistance. The hardness of cemented carbide can reach more than HRA90, while the hardness of high-speed steel can only reach about HRC70.
Toughness: Relatively speaking, high-speed steel has better toughness, while cemented carbide is relatively fragile.
In terms of performance: both have the characteristics of large hardness, high strength, good toughness, red hardness, wear resistance, heat resistance and process performance, and these characteristics will vary depending on the grade. Generally speaking, the hardness, red hardness, wear resistance and heat resistance of cemented carbide are better than those of high-speed steel.
Carbide and high-speed steel are common tool materials, each with its own unique characteristics.
Carbide has the characteristics of high hardness, high wear resistance, high corrosion resistance and high bending resistance. It can maintain good hardness at high temperatures and has excellent thermal and chemical stability.
High-speed steel is high-carbon and high-alloy steel. It can be divided into tungsten series and molybdenum series steel according to its chemical composition. It can be divided into ordinary high-speed steel and high-performance high-speed steel according to its cutting performance. High-speed steel must be strengthened by heat treatment.
