The cold working of the steel is medium in plasticity, the cutting performance is general, the welding performance is poor, the sensitivity to white spots is large, and the temper brittleness is obtained.

100Cr6 is one of the most commonly used high carbon chromium bearing steels with high hardenability and high and uniform hardness after heat treatment. The wear resistance is better than GCr9, the contact fatigue strength is high, the dimensional stability and corrosion resistance are good, the cold deformation plasticity is medium, the machinability is general, the weldability is poor, the formation is sensitive to white spots, and there is a first type of temper brittleness. In the manufacture of ball bearings, it is used to roll H-class to C-class bearing sleeves with a wall thickness of 12 mm and an outer diameter of <250 mm, steel balls with a diameter of 25.4-50.8 mm, and rollers with a diameter of <22 mm, which can also be used as a bearing. Heavy load. High wear resistance is required. High elastic limit. Other mechanical parts with high contact fatigue strength and various precision measuring tools such as cold die.
