Material properties and application range of GCr15 bearing steel ball

- Sep 12, 2018-

GCr15 bearing steel ball is a steel ball made of GCr15 bearing steel, and GCr15 refers to a high carbon chromium bearing steel with less alloy content. After quenching and low temperature tempering, it has high hardness and uniform structure. Good wear resistance and high contact fatigue performance.


GCr15 bearing steel ball manufacturing material GCr15 is actually one of the most commonly used high carbon chromium bearing steel, with high hardenability, high and uniform hardness after heat treatment. Because of its better wear resistance than GCr9, high contact fatigue strength, good dimensional stability and corrosion resistance, GCr15 bearing steel balls also have the same characteristics.


For the time being, the GCr15 bearing steel ball is characterized by magnetic, ferritic steel, oily packaging, HRC60-66; the product has been widely used in high-speed low-noise bearings, bicycles, motorcycles, automobiles, rails, universal Balls, bags, electronics, can also be used to grind other media.
