14NiCr14 carburizing steel
14NiCr14 is a widely used high-grade carburizing steel, which has high strength, ductility and hardenability as compared with 15Cr and 20Cr steels. Quenching and tempering at low temperature or high temperature tempering, have good mechanical properties, low temperature impact toughness, notch sensitivity, machinability and weldability is good, but the temper brittleness, white point of high sensitivity After carburizing are required for secondary quenching, special circumstances also need cold treatment.
