Show full description

Alloy Steel Round Bar 52100

Alloy Steel 52100 round bar is a high-carbon, chromium-bearing steel renowned for exceptional hardness, wear resistance, and fatigue strength—qualities that make it a premier choice for bearings, races, shafts, punches, and high-precision mechanical components. Its fine-grain microstructure supports excellent dimensional stability and surface finish, especially after heat treatment. This material also performs well in demanding rotating or load-bearing environments, maintaining strength under stress and consistent frictional conditions. With its combination of durability and machinability, 52100 is widely used in automotive, aerospace, tooling, and industrial applications where long service life is essential. Available in multiple diameters and custom cut options, it supports both prototyping and large-scale manufacturing.
