Hardness: It has excellent hardness, typically reaching a hardness of about 60-65 HRC (Rockwell
hardness scale), which is among the highest for steels used in industrial applications.
Wear Resistance: Its high carbon content and chromium alloying provide exceptional wear resistance,
making it suitable for applications where components are subjected to heavy loads and sliding friction.
Toughness: Despite its high hardness, 52100 steel retains good toughness, which is essential for resisting
fracture and fatigue in bearing applications.
Machinability: While it can be more challenging to machine compared to lower carbon steels due to its
hardness, it can still be machined using appropriate techniques and tooling.
Applications: Besides bearings, 52100 steel is also used in various applications such as roller bearings,
ball bearings, automotive parts, surgical instruments, and even in some knives and tools.
