High-speed steel cutter classification

According to different manufacturing processes, high-speed steel can be divided into high-speed steel melting and powder metallurgy high-speed steel. ① smelting high-speed steel: ordinary high-speed steel and high-speed steel are produced by melting method. After smelting, casting and rolling process, they are made into knives. Smelting high-speed steel prone to serious problems is carbide segregation, […]
