GCr15 /SAE52100/EN31 alloy steel round bar for bearing
Product Introduction
GCr15 refers to a high carbon and chromium bearing steel with less alloy content. After quenching and low temperature tempering, it has high hardness, uniform structure, good wear resistance and high contact fatigue performance.
Features
1. 1 A kind of high carbon and chromium bearing steel which most widely used with a good permance and less alloy content.
2. 2. High hardenability and good comprehensive performance.
3. 3. Good machinability after spheroidizing annealing
4. 4. High hardness, uniform organization, good wear resistance, high contact fatigue performance after quenching and tempering.
5. 5. Good hot working performance
