52100 Chromium Steel Sphere, Grade G25, Mirror-Like Finish, Precision Tolerance, A295, 3/4" Diameter, 0.000024" Sphericity (Pack of 25)

The 52100 chromium steel sphere has a reflective finish, meets American Society for testing and materials international A295 specifications, meets grade 25 sphere tolerance standards, and has a precision tolerance. The 52100 Alloy steel grade has a high carbon and chromium content for high strength, high resistance to corrosion and wear, and good machinability. This Material can be heat treated for higher hardness. The reflective finish provides a bright, mirror-like appearance. Steel is an iron Alloy with carbon and other elements that modify the steel to achieve specific properties. In general, steels with higher carbon content have greater strength, hardness, and wear resistance, while those with lower carbon content have more formability, weld ability, and toughness.
