Characteristics of SKH-51: SKH-51 is an internationally recognized tungsten molybdenum series ductile high-speed steel. The carbide particles of this steel are small and uniform, with high toughness, excellent cutting performance, and good thermoplastic properties. It has good wear resistance, especially can resist high temperatures of 600 ℃ and is not easily softened. It has good red hardness and can reach a hardness of 64HRC after heat treatment quenching. Its wear resistance is twice as high as that of high chromium high carbon steel, and its machinability is 1.5 times stronger. The disadvantage is that the heat treatment process is difficult and the cost of use is high.
KED produces various precision mold inserts, needle inserts, cores, assistants, top pins, flat top pins, support pins, drivers, punches, punch pins, cylindrical pins, non-standard top pins for molds, precision guide column guide sleeves, imported mold springs, precision thread processing, square, elliptical, flat, fan-shaped, eccentric workpieces, precision circular shaft workpieces, diamond shaped, polygonal and other shaped workpieces.
