STEEL BALL

High carbon chromium bearing steel ball


High-carbon chromium steels usually contain 1% C and 1.5% Cr and are quenched at 780 to 850 degrees. Then, tempering is performed at 140-160 degrees to make the hardness of HRC 62-65. Type 1 and Type 2 are used for bearing balls or roller bearings, and Type 3 is used for large roller bearings.

Stainless steel ball


Stainless steel is called stainless steel because it adds more than 12% Cr to create a "Passive film" that acts as a protective film to maintain corrosion resistance of stainless steel.

Carbon steel ball 


It refers to a river containing 0.02-2.06% C in carbon steel. Carbon steel changes its mechanical properties by heat treatment such as quenching, tempering, and annealing, and its use is wide.
